Hartmut 1ec56aac13 docs: expand .env.example with full documented variable reference
Replaces the minimal 17-line stub with a comprehensive, commented
reference covering all env vars: app/auth, database, Redis, SMTP,
pgAdmin, logging, security/cron, and testing flags. Each section
explains when the var is required and what values are expected.

# ─────────────────────────────────────────────────────────────────────────────
# CapaKraken — environment variable reference
#
# Copy this file to .env and fill in the values before running the app.
# Lines starting with # are comments. Lines with no value are optional.
#
# IMPORTANT: Never commit your actual .env file — it is gitignored.
# ─────────────────────────────────────────────────────────────────────────────
# ─── App / Auth ──────────────────────────────────────────────────────────────
# REQUIRED — Public URL of the app (with scheme, no trailing slash).
# Used in email links (invites, password reset) and as the Auth.js base URL.
# Must use https:// in production.
NEXTAUTH_URL=https://capakraken.example.com
# REQUIRED — Secret used to sign and encrypt JWTs and session cookies.
# Generate one with: openssl rand -base64 32
# Must not be a known placeholder value in production (e.g. "changeme").
NEXTAUTH_SECRET=
# ─── Database ────────────────────────────────────────────────────────────────
# REQUIRED — PostgreSQL connection string.
# When running with Docker Compose the app container uses the Docker-internal
# host (postgres:5432); the host-level connection (for pnpm dev on the host)
# uses localhost:5433 (the published port).
DATABASE_URL=postgresql://capakraken:capakraken_dev@localhost:5433/capakraken
# ─── Redis ───────────────────────────────────────────────────────────────────
# REQUIRED for SSE (real-time updates) and rate limiting.
# When using Docker Compose this is handled automatically inside the container
# (redis://redis:6379). Only needed when running `pnpm dev` directly on the host.
# REDIS_URL=redis://localhost:6380
# Controls which backend is used for rate limiting.
# Values: "redis" (default, requires REDIS_URL) | "memory" (in-process, not
# suitable for multi-instance deployments).
# RATE_LIMIT_BACKEND=redis
# ─── SMTP ────────────────────────────────────────────────────────────────────
#
# SMTP settings can be configured here OR via the Admin → Settings UI.
# Environment variables override the database values at runtime.
# If neither is set, email sending is silently skipped (logged at warn level).
#
# For local development the Docker Compose stack includes MailHog
# (http://localhost:8025) — no SMTP configuration is needed there.
# SMTP_HOST=smtp.example.com
# SMTP_PORT=587
# SMTP_USER=no-reply@example.com
# SMTP_PASSWORD=
# SMTP_FROM=CapaKraken <no-reply@example.com>
# SMTP_TLS=true # "true" = SMTPS (port 465); "false" = STARTTLS or plain
# ─── pgAdmin (dev / Docker Compose only) ─────────────────────────────────────
# REQUIRED when starting Docker Compose with the `full` profile.
# Used as the password for the pgAdmin web UI (http://localhost:5050).
PGADMIN_PASSWORD=
# Email shown on the pgAdmin login screen (default: admin@capakraken.dev).
# PGADMIN_EMAIL=admin@capakraken.dev
# ─── Logging ─────────────────────────────────────────────────────────────────
# Log verbosity. Values: trace | debug | info | warn | error | fatal
# Default: info
# LOG_LEVEL=info
# ─── Security / Cron ─────────────────────────────────────────────────────────
# Secret used to authenticate requests to cron endpoints (/api/cron/*).
# Generate one with: openssl rand -hex 32
# If not set, cron endpoints are disabled.
# CRON_SECRET=
# ─── Testing (never enable in production) ────────────────────────────────────
# Disables rate limiting and session tracking during end-to-end tests.
# MUST be "false" or unset in production — the runtime will refuse to start
# if this is "true" and NODE_ENV is "production".
# E2E_TEST_MODE=false
