Encrypt Proxmox server passwords and VM cloud-init passwords in the database:
- Add backend/app/crypto.py: Fernet-based encrypt/decrypt helpers + EncryptedString
SQLAlchemy TypeDecorator (transparent to all existing code, no API changes)
- Add FERNET_KEY config field (env var); without it values stay plaintext for
backward compatibility, with a logged warning
- Update models.py: ProxmoxServer.password and VMInstance.cloud_init_password
now use EncryptedString(255) instead of String(255)
- Add migration 14 in migrations/migrations.py: idempotent re-encryption of
existing plaintext rows (skipped when FERNET_KEY is not set)
CSRF analysis:
- /api/auth/change-password is protected by JWT Bearer token (Authorization header)
- Browsers cannot auto-include Authorization headers cross-site → CSRF is not
applicable here; added explanatory comment
Improve migration loading:
- Add migrations/__init__.py to make it a proper Python package
- Replace fragile importlib dynamic loading in main.py with a standard import
