fix: simplify ComposeView overlay without custom lifecycle owner

- Remove complex OverlayLifecycleOwner implementation
- Remove ViewTreeLifecycleOwner references (not available in this API level)
- Use basic ComposeView without explicit lifecycle management
- Let ComposeView handle its own lifecycle in overlay context

Some Android versions support ComposeView in overlay without explicit lifecycle.
If this still fails, we'll fall back to View-based FAB implementation.
