feat(EditableCell): add signal disposal handling and logging

- Introduced `is_disposed` signal to track component disposal state.
- Added `on_cleanup` hook to set disposal flag and log when the component is disposed.
- Enhanced signal access with `log_signal_get` to prevent usage after disposal.
- Improved input, focus, and blur handlers to respect disposal state.
- Ensured robust handling of signals during the component's lifecycle.

This improves resilience and debugging for EditableCell, especially in dynamic UI contexts.
