Add patch application state management in ServeSession

Browse source 
- Introduced a new flag `__applyingPatch` to track the patch application state, preventing `DescendantAdded` events during reconciliation.
- Updated the `__applyPatch` method to set and clear the `__applyingPatch` flag appropriately, enhancing control over script updates.
- Added checks in the `__connectScriptsOnlyWatchers` method to avoid processing during patch application.

These changes aim to improve the reliability of script handling during patch operations and prevent unintended side effects.
