feat: Add combined track functionality with repository and service layers

- Introduced CombinedTrackModel, CombinedTrackCreate, and CombinedTrackRepository for managing combined tracks. - Implemented logic to create combined tracks based on existing tracks between two stations. - Added methods to check for existing combined tracks and retrieve constituent track IDs. - Enhanced TrackModel and TrackRepository to support OSM ID and track updates. - Created migration scripts for adding combined tracks table and OSM ID to tracks. - Updated services and API endpoints to handle combined track operations. - Added tests for combined track creation, repository methods, and API interactions.
