fix: add lifecycle owner to ComposeView in overlay

- Create OverlayLifecycleOwner implementing LifecycleOwner and SavedStateRegistryOwner
- Set ViewTreeLifecycleOwner and ViewTreeSavedStateRegistryOwner on ComposeView
- Manage lifecycle states (onCreate, onStart, onResume, onDestroy) for overlay
- Fixes: ViewTreeLifecycleOwner not found exception when using ComposeView in overlay

Error: java.lang.IllegalStateException: ViewTreeLifecycleOwner not found
Solution: Provide custom lifecycle owner for overlay context
