## Summary
This PR introduces support for retrieving and displaying enabled time series
query languages configured at the broker level. Key updates include:
- **Broker API**: Added a new REST endpoint `/timeseries/languages` in
PinotBrokerTimeSeriesConfigResource to return the list of configured timeseries
languages from broker settings.
- **Controller Proxy API**: Extended `PinotBrokerRestletResource` with
`/brokers/timeseries/languages` to fetch languages from a broker instance via
HTTP, with error handling and fallback logic.
- **UI Enhancements:** Updated the `TimeseriesQueryPage` React component to
dynamically fetch and display supported timeseries query languages:
- Query editor and form controls are disabled when no languages are
enabled.
- A warning banner is shown if no languages are configured.
- Language selector dropdown is populated based on broker response.
- **Client API**: Added `getTimeSeriesLanguages()` to `requests/index.ts`
for UI to call the new controller endpoint.
Since the response from the broker can be variable, the UI components are
not hidden but disabled for editing.
## Testing
Verified for both cases where timeseries is enabled and not enabled.
