feat: Add API Key support for MCP authentication

- New db model: api_keys table with bcrypt-hashed keys
- New API: POST/GET/DELETE /v3/access/api-keys endpoints
- MCP _resolve_token: validates API keys, resolves to 5-min JWT
- API keys inherit the creating user's RBAC permissions
- MCP auth supports both JWT (24h) and API key (permanent) tokens
