WIP: Enable dynamic AIS stream handling based on user location and map focus.

- Prevent AIS stream from starting immediately; start upon user interaction.
- Add `ais_stream_started` state for WebSocket management.
- Extend `useRealAISProvider` with `userLocationLoaded` and `mapFocused` to control stream.
- Update frontend components to handle geolocation and map focus.
- Exclude test files from compilation

Introduce WebSocket integration for AIS services

- Added WebSocket-based `useRealAISProvider` React hook for real-time AIS vessel data.
- Created various tests including unit, integration, and browser tests to validate WebSocket functionality.
- Added `ws` dependency to enable WebSocket communication.
- Implemented vessel data mapping and bounding box handling for dynamic updates.
