security: fix critical vulnerabilities (issues #2 and #3)
Issue #2: Unprotected Chat Summary Trigger (CRITICAL)
- Add authentication and admin authorization to /trigger endpoint
- Add path validation to prevent directory traversal
- Block access to system directories (/etc, /root, /sys, /proc, /boot)
- Add tests for unauthorized access and invalid paths
Issue #3: Exception Information Disclosure (HIGH)
- Replace raw exception messages with generic errors
- Log full exception details server-side with logger.exception()
- Affected files: auth.py, files.py, passkey.py, opc_agents.py
- Prevents information leakage about system architecture
Security Impact:
- Prevents unauthenticated file system writes
- Reduces reconnaissance opportunities for attackers
- Maintains security while preserving debugging capability
Tests: 214 passing, all security tests verified
