fix: Send bounds to server after map initialization to trigger historical loading

- Added sendBoundsToServer() call after map_ready event
- Previously only saveMapState was called which doesn't send bounds
- This ensures historical packets are loaded on initial page load
- Also added to retry logic for reliability

The issue was that bounds_changed event was never triggered on initial load, preventing historical packets from being fetched.
