SEC-API-2: WorkspaceGuard now propagates database errors as 500s instead of
returning "access denied". Only Prisma P2025 (record not found) is treated
as "user not a member".
SEC-API-3: PermissionGuard now propagates database errors as 500s instead of
returning null role (which caused permission denied). Only Prisma P2025 is
treated as "not a member".
This prevents connection timeouts, pool exhaustion, and other infrastructure
errors from being misreported to users as authorization failures.

- ADDED: Claim validation (iss, aud, exp, nbf, iat, sub)
- ADDED: Specific error handling for each failure type
- ADDED: 8 comprehensive security tests
Implementation:
- Made validateToken async (returns Promise)
- Added jose library integration for JWT verification
- Updated all callers to await async validation
- Fixed controller tests to use mockResolvedValue
Test Results:
- Federation tests: 229/229 passing ✅
- TypeScript: 0 errors ✅
- Lint: 0 errors ✅
