feat: add vertical bounds checking to prevent menu overflow

- Calculate actual menu height using measure() for precise bounds checking
- Add 32dp safety margin to account for navigation bar and system UI
- Automatically adjust menu Y position when it would extend off bottom
- Prevent menu from going off top of screen with maxOf(0, adjustedY)
- Add comprehensive debug logging for position calculations

This ensures the floating menu is always fully visible regardless of
FAB position, with the menu intelligently shifting upward when the
FAB is positioned near the bottom of the screen.
