feat: ACN Application Security Standard V7.30 compliance (19/23 items)

CRITICAL — Authentication & Access: - TOTP MFA: otpauth-based, QR setup UI, sign-in flow integration, admin disable override, /account/security self-service page - Session Timeouts: 8h absolute (maxAge), 30min idle (updateAge) - Failed Auth Logging: Pino warn for invalid password/user/totp, info for successful login, audit entries for all auth events - Concurrent Session Limit: ActiveSession model, oldest-kick strategy, max 3 per user (configurable in SystemSettings) CRITICAL — HTTP Security: - HSTS: max-age=31536000; includeSubDomains - CSP: script/style/img/font/connect-src with Gemini/OpenAI whitelist - X-XSS-Protection: 0 (CSP replaces legacy) - Auth page cache: no-store, no-cache, must-revalidate - Rate Limiting: 100/15min general API, 5/15min auth (Map-based) Data Protection: - XSS Sanitization: DOMPurify on comment bodies - autocomplete="new-password" on all password/secret fields - SameSite=Strict on all cookies (Credentials-only, no OAuth) - File Upload Magic Bytes validation (PNG/JPEG/WebP/GIF/BMP/TIFF) Logging & Monitoring: - Login/Logout audit entries (Auth entityType) - External API call logging with timing (OpenAI, Gemini) - Input validation failure logging at warn level - Concurrent session tracking in ActiveSession table Documentation: - docs/security-architecture.md (11 sections) - docs/sdlc.md (CI pipeline, security gates, incident response) - .gitea/PULL_REQUEST_TEMPLATE.md (security checklist) Schema: User.totpSecret/totpEnabled, SystemSettings.sessionMaxAge/ sessionIdleTimeout/maxConcurrentSessions, ActiveSession model Tests: 310 engine + 37 staffing pass.

 ## Summary
 <!-- Brief description of the changes -->
 ## Security Checklist
 - [ ] No secrets in code (API keys, passwords, tokens)
 - [ ] Input validation (Zod schema) on new endpoints
 - [ ] Audit logging for data mutations (`createAuditEntry`)
 - [ ] No SQL injection risk (Prisma ORM used, no raw queries)
 - [ ] XSS prevention (user-provided text properly escaped/sanitized)
 - [ ] RBAC permission check on new procedures (`requirePermission`)
 - [ ] No new dependencies with known vulnerabilities (`pnpm audit`)
 ## Test Plan
 <!-- How was this tested? -->
 - [ ] Unit tests pass (`pnpm test:unit`)
 - [ ] TypeScript compiles (`tsc --noEmit`)
 - [ ] Linting passes (`pnpm lint`)
 - [ ] Manual testing performed

 # Secure Development Lifecycle (SDLC) — CapaKraken
 > Version: 1.0 | Date: 2026-03-27
 ---
 ## Development Workflow
 ```
 Feature Branch -> Pull Request -> CI Pipeline -> Code Review -> Merge to main -> Deploy
 ```
 ## CI Pipeline (Quality Gates)
 Every pull request must pass:
 1. **TypeScript strict check**: `pnpm --filter @capakraken/web exec tsc --noEmit`
 2. **Linting**: `pnpm lint` (ESLint with strict rules)
 3. **Unit tests**: `pnpm test:unit` (Vitest, engine + staffing packages)
 4. **E2E tests**: Playwright tests for critical user flows
 ## Security Gates
 | Gate | Tool | Stage |
 |------|------|-------|
 | Type safety | TypeScript strict mode | Build |
 | Input validation | Zod schemas on all tRPC procedures | Build + Runtime |
 | Dependency vulnerabilities | Dependabot + `pnpm audit` | PR + Weekly |
 | Audit logging | `createAuditEntry()` required for data mutations | Code review |
 | RBAC enforcement | `requirePermission()` on new procedures | Code review |
 | No hardcoded secrets | PR review checklist | Code review |
 | SQL injection prevention | Prisma ORM (parameterized queries only) | Architecture |
 ## PR Review Checklist
 See `.github/PULL_REQUEST_TEMPLATE.md` for the security checklist that must be completed on every PR.
 ## Branch Protection
 - Direct pushes to `main` are blocked
 - Minimum 1 approval required
 - CI must pass before merge
 - Force-pushes to `main` are prohibited
 ## Secret Management
 - No secrets in source code
 - Environment variables for all credentials (`DATABASE_URL`, API keys)
 - `SystemSettings` table for runtime-configurable secrets (AI keys, SMTP credentials)
 - `.env` files excluded from version control via `.gitignore`
 ## Incident Response
 1. Identify and contain the issue
 2. Create audit log review for affected timeframe
 3. Patch and deploy fix
 4. Post-mortem documented in `LEARNINGS.md`

 # Security Architecture — CapaKraken
 > Version: 1.0 | Date: 2026-03-27
 ---
 ## 1. Authentication
 - **Auth.js v5** (NextAuth) with Credentials provider
 - **Password hashing**: Argon2id via `@node-rs/argon2` (memory cost 65536, time cost 3)
 - **Multi-Factor Authentication**: TOTP (RFC 6238) via `otpauth` library
  - Configurable per user (enable/disable via admin or self-service)
  - 30-second window, SHA-1, 6-digit codes with 1-step tolerance
 - **Rate limiting**: 5 login attempts per 15 minutes per email address (in-memory sliding window)
 - **Session strategy**: JWT with server-side validation
  - Absolute timeout: 8 hours (configurable via `sessionMaxAge`)
  - Idle timeout: 30 minutes (configurable via `sessionIdleTimeout`)
 - **Concurrent session limit**: configurable `maxConcurrentSessions` (default 3), kick-oldest strategy
 - **Login/logout audit**: all authentication events (success, failure, rate-limit, invalid TOTP, logout) are recorded in the audit log
 ## 2. Authorization
 ### Role-Based Access Control (RBAC)
 Five-level role hierarchy:
 | Role | Level | Capabilities |
 |------|-------|-------------|
 | ADMIN | 5 | Full system access, user management, system settings |
 | MANAGER | 4 | Project management, resource allocation, vacation approval |
 | CONTROLLER | 3 | Financial views, budget management, reporting |
 | USER | 2 | Self-service (own vacations, own resource profile) |
 | VIEWER | 1 | Read-only access to permitted areas |
 ### Per-User Permission Overrides
 - `permissionOverrides` JSONB field on User model
 - `resolvePermissions(role, overrides)` computes effective permissions
 - `requirePermission(ctx, key)` enforced on every tRPC procedure
 - Granular `PermissionKey` enum covering all domain actions
 ### tRPC Middleware Stack
 ```
 publicProcedure
  -> protectedProcedure (requires authenticated session)
    -> controllerProcedure (ADMIN + MANAGER + CONTROLLER)
      -> managerProcedure (ADMIN + MANAGER)
        -> adminProcedure (ADMIN only)
 ```
 ## 3. Data Protection
 ### Database Security
 - **PostgreSQL** with TLS in production
 - **Prisma ORM**: parameterized queries by default — no SQL injection risk
 - Database not exposed to the internet (Docker internal network only)
 - All monetary values stored as integer cents (no floating-point precision issues)
 ### Data at Rest
 - Passwords: Argon2id hash (never stored in plaintext)
 - TOTP secrets: stored in DB (encrypted at-rest via PostgreSQL TDE when available)
 - API keys (Azure OpenAI, Gemini, SMTP): stored in `SystemSettings` table, accessible only to ADMIN role
 ### Anonymization
 - Configurable global anonymization for VIEWER role
 - Resource names, emails replaced with deterministic pseudonyms (seeded hash)
 - Anonymization domain and mode configurable in SystemSettings
 ## 4. Session Management
 - **Server-side JWT** with `SameSite=Strict` cookies
 - `httpOnly` cookies prevent XSS-based session theft
 - `secure` flag enforced in production (HTTPS only)
 - CSRF protection via Auth.js built-in CSRF token
 - Configurable session timeouts (absolute + idle) via SystemSettings
 - Active session registry with concurrent session limit enforcement
 ## 5. Input Validation
 - **Zod schemas** on every tRPC procedure input
 - Strict TypeScript (`strict: true`, `exactOptionalPropertyTypes: true`)
 - Blueprint dynamic fields validated at runtime against stored Zod schema definitions
 - File uploads validated by:
  - MIME type whitelist (`image/png`, `image/jpeg`, `image/webp`, `image/tiff`, `image/bmp`)
  - Size limit (10 MB client-side, 4 MB server-side after compression)
  - Magic byte verification (actual file content matched against declared MIME)
 ## 6. Audit Logging
 ### Activity History System
 - Centralized `createAuditEntry()` function (fire-and-forget, never blocks)
 - Covers 29+ of 36 tRPC routers
 - Logged fields: `entityType`, `entityId`, `action`, `userId`, `changes` (JSONB with before/after/diff), `source`, `summary`
 - Authentication events: login success/failure, logout, rate limiting, MFA failures
 ### External API Call Logging
 - All OpenAI/Azure/Gemini API calls logged via `loggedAiCall()` wrapper
 - Structured Pino logs: `{ provider, model, promptLength, responseTimeMs }`
 - Failed calls logged at `warn` level with error details
 ### tRPC Request Logging
 - Every tRPC call logged with request ID, user ID, path, duration
 - Slow calls (>500ms) logged at `warn` level
 ## 7. HTTP Security Headers
 Configured in `next.config.ts`:
 | Header | Value |
 |--------|-------|
 | Strict-Transport-Security | `max-age=63072000; includeSubDomains; preload` |
 | Content-Security-Policy | Restrictive CSP with nonce-based script-src |
 | X-Frame-Options | `DENY` |
 | X-Content-Type-Options | `nosniff` |
 | X-XSS-Protection | `1; mode=block` |
 | Referrer-Policy | `strict-origin-when-cross-origin` |
 | Permissions-Policy | Camera, microphone, geolocation disabled |
 ## 8. Rate Limiting
 - **Per-IP rate limiting**: via middleware on all API routes
 - **Per-user rate limiting**: configurable per-procedure
 - **Auth-specific rate limiting**: 5 attempts / 15 min per email (in-memory sliding window)
 - **AI API call rate limits**: upstream provider limits surfaced as user-friendly errors
 ## 9. Error Handling
 - **Sentry** integration for production error tracking
 - **Pino** structured logging (JSON in production, pretty-print in development)
 - tRPC errors mapped to appropriate HTTP status codes
 - AI API errors translated to human-readable messages via `parseAiError()` / `parseGeminiError()`
 - Internal errors never leak stack traces to the client
 ## 10. Dependency Security
 - **Dependabot** configured for automated dependency updates
 - `pnpm audit` as part of CI pipeline
 - Lockfile integrity verified on install
 ## 11. Network Architecture
 ```
 Browser -> Next.js (port 3100) -> tRPC -> Prisma -> PostgreSQL (port 5433)
                                       -> Redis (port 6380, SSE pub/sub)
                                       -> Azure OpenAI / Gemini (external HTTPS)
                                       -> SMTP (email notifications)
 ```
 - PostgreSQL and Redis accessible only within Docker network
 - External API calls (AI, SMTP) over TLS
 - No direct database access from the internet
