feat: add API token authentication (closes #87)

- Add api_tokens table migration (007)
- Add APIToken model with CRUD operations
- Generate tokens with upaas_ prefix + 32 hex chars
- Store SHA-256 hash of tokens (not plaintext)
- Update APISessionAuth middleware to check Bearer tokens
- Add POST/GET/DELETE /api/v1/tokens endpoints
- Token creation returns plaintext once; list never exposes it
- Expired and revoked tokens are rejected
- Tests for creation, listing, deletion, bearer auth, revocation
