fix(ui): resolve MainActivity crash in smoke tests by reordering initialization and guarding MapLibre

- Ensure lateinit UI properties are assigned before setupMap() and setupHandlers()
- Skip MapLibre initialization and lifecycle calls when NavApplication.isTesting is true to avoid emulator Vulkan crashes
- Guard MapView lifecycle calls in onResume, onStart, etc.
