fix: Update tests and normalize callsigns for new URL structure

- Update callsign view tests to use LiveView instead of redirect assertions
- Normalize callsigns to uppercase when extracting from path params
- Handle empty/nil callsigns gracefully in mount function
- Tests now verify map display rather than redirect behavior

All tests now pass with the new direct station URL implementation.
