fix: Keep traffic pattern and runway active when collapsing navigation panel

- Changed collapse behavior: only collapses UI details, not pattern display
- Pattern and runway selection now persist when user collapses panel
- Differentiates between collapse (hide details) and cancel (deactivate route)
- Improves user workflow by maintaining pattern visibility during compact mode
