feat: add re-show drawer button and auto-update functionality

- Add "RESULTS" menu item to floating FAB for re-showing drawer
- Implement showLastDetectionResult() to retrieve and display last result
- Update ResultsBottomDrawer to auto-refresh when new detection occurs while visible
- Replace early return with updateDrawerContent() for seamless drawer updates
- Maintain drawer state (collapsed/expanded) during content updates
