feat: Add authentication debug and test scripts

- Add debug-auth.sh to diagnose authentication issues
  - Checks .env file content
  - Verifies environment variables in container
  - Tests bcrypt password verification
  - Shows config loading status
  - Displays recent auth logs

- Add test-auth-api.sh to test API endpoints directly
  - Tests login endpoint with curl
  - Shows raw API responses
  - Tests auth status endpoint

These scripts help troubleshoot authentication problems by showing
exactly what's happening at each step of the auth process.
