Merge develop into main (#150)

- Update `Configuration` to use C++ vector instead of C arrays
- Rename `Desktop` app to `Launcher`
- Fix for hard-coded app start of `Launcher` and `CrashDiagnostics` apps.
- Ensure `Launcher` icons are clickable, even if they're not loading.
- Don't show error scenario for SD card in statusbar when SD card status is unknown (this happens during Mutex timeout due to LVGL rendering delays)
- Cleanup deprecated `Mutex` methods.
- `hal::getConfiguration()` now returns a pointer instead of a reference, just like `tt:getConfiguration()`
