This PR fixes a security vulnerability in the authentication logic. Previously, verifyToken did not check if a token was blacklisted (e.g., after logout), allowing revoked tokens to be used until their natural expiration. This change adds a call to isTokenBlacklisted within verifyToken to ensure revoked tokens are rejected immediately. Verified with unit tests mocking Redis and Prisma.

- Added explicit check to `AuthService.verifyToken` to reject tokens that are present in the blacklist (Redis).
- Ensures that logged-out users (or revoked tokens) cannot continue to access protected resources until token expiration.
- This addresses a logic flaw where `verifyToken` relied only on signature verification and user existence.
