- Comprehensive error handling with proper HTTP status codes

Implementation:
- Enhanced src/middleware/auth.py (415 lines)
  - JWTConfig class for token management
  - create_jwt_token() for token generation
  - decode_jwt_token() for token validation
  - @verify_tenant_context decorator for auth middleware
  - @verify_role decorator for RBAC
  - verify_resource_access() for row-level security
  - log_request_context() for audit logging

Testing:
- 52 comprehensive test cases covering all features
- 100% pass rate with fast execution (0.15s)
- Test categories: JWT, multi-tenant, RBAC, RLS, logging, integration
- Full coverage of error scenarios and edge cases

Documentation:
