feat(#351): Implement RLS context interceptor (fix SEC-API-4)
Implements Row-Level Security (RLS) context propagation via NestJS interceptor and AsyncLocalStorage.

Core Implementation:
- RlsContextInterceptor sets PostgreSQL session variables (app.current_user_id, app.current_workspace_id) within transaction boundaries
- Uses SET LOCAL for transaction-scoped variables, preventing connection pool leakage
- AsyncLocalStorage propagates transaction-scoped Prisma client to services
- Graceful handling of unauthenticated routes
- 30-second transaction timeout with 10-second max wait

Security Features:
- Error sanitization prevents information disclosure to clients
- TransactionClient type provides compile-time safety, prevents invalid method calls
- Defense-in-depth security layer for RLS policy enforcement

Quality Rails Compliance:
- Fixed 154 lint errors in llm-usage module (package-level enforcement)
- Added proper TypeScript typing for Prisma operations
- Resolved all type safety violations

Test Coverage:
- 19 tests (7 provider + 9 interceptor + 3 integration)
- 95.75% overall coverage (100% statements on implementation files)
- All tests passing, zero lint errors

Documentation:
- Comprehensive RLS-CONTEXT-USAGE.md with examples and migration guide
