Analytics: Rename transportMode to themeId in theme selection event (#…

…593)

### TL;DR
Updated theme selection analytics to track theme IDs instead of transport modes

### What changed?
- Renamed `transportMode` parameter to `themeId` in `ThemeSelectedEvent`
- Simplified theme selection tracking by removing transport mode conversion
- Updated corresponding test cases to reflect the new parameter name

### How to test?
1. Navigate to theme selection screen
2. Select different themes
3. Verify analytics events are logged with theme IDs
4. Run unit tests to confirm analytics tracking behavior

### Why make this change?
Tracking raw theme IDs provides more accurate analytics data compared to converting them to transport modes, which may not always have a direct mapping. This change simplifies the analytics implementation and makes it more maintainable.
