- Redact Bearer tokens from error stacks/messages before logging to
prevent session token leakage into server logs
- Add logger.warn for non-Error thrown values in verifySession catch
block for observability
- Add tests for token redaction and non-Error warn logging

Replace broad "expired" and "unauthorized" substring matches with specific
patterns to prevent infrastructure errors from being misclassified as auth
errors:
- "expired" -> "token expired", "session expired", or exact match "expired"
- "unauthorized" -> exact match "unauthorized" only
This prevents TLS errors like "certificate has expired" and DB auth errors
like "Unauthorized: Access denied for user" from being silently swallowed
as 401 responses.

Verify verifySession returns null when getSession throws non-Error
values (strings, objects) rather than crashing.

verifySession now allowlists known auth errors (return null) and re-throws
everything else as infrastructure errors. OIDC health check escalates to
error level after 3 consecutive failures.

- Wire COOKIE_DOMAIN env var into BetterAuth cookie config
- Add URL validation for TRUSTED_ORIGINS (rejects non-HTTP, invalid URLs)
- Include original parse error in validateRedirectUri error message
- Distinguish infrastructure errors from auth errors in verifySession
(Prisma/connection errors now propagate as 500 instead of masking as 401)

- Add getAuthConfig() to AuthService (email always, OIDC when enabled)
- Add GET /auth/config public endpoint with Cache-Control: 5min
- Place endpoint before catch-all to avoid interception

- Integrated BetterAuth library for modern authentication
- Added Session, Account, and Verification database tables
- Created complete auth module with service, controller, guards, and decorators
- Implemented shared authentication types in @mosaic/shared package
- Added comprehensive test coverage (26 tests passing)
- Documented type sharing strategy for monorepo
- Updated environment configuration with OIDC and JWT settings
Key architectural decisions:
- BetterAuth over Passport.js for better TypeScript support
- Separation of User (DB entity) vs AuthUser (client-safe subset)
- Shared types package to prevent FE/BE drift
- Factory pattern for auth config to use shared Prisma instance
Ready for frontend integration (Issue #6).
