feat: remove speed limit tunnel binding and add migration cleanup

- Remove tunnel binding UI from speed limit page (no more Select component)
- Remove /api/v1/speed-limit/tunnels route alias
- Simplify CreateSpeedLimit/UpdateSpeedLimit to not accept tunnel parameters
- Add schema migration v4 to clear historical tunnel_id/tunnel_name bindings
- Update contract tests to verify tunnel binding is ignored
- Add limiter sync failure tests for forward-level rate limiting
