security: bound password inputs, configure pino redact, patch deps (#36 #46 #58)

#36 CRITICAL: add .max(128) to all password Zod schemas to prevent
Argon2-based DoS from unbounded password strings.

#46 HIGH: configure pino redact paths so passwords/tokens/cookies/TOTP
secrets are never serialized in logs.

#58 MEDIUM: upgrade dompurify to ^3.4.0 and add pnpm overrides for
brace-expansion (>=5.0.5) and esbuild (>=0.25.0) to patch known CVEs.
Vite moderate (path traversal, dev-only) remains — requires vitest 3.x
major upgrade, deferred.
