fix(editable cell): (in progress) improve EditableCell component to handle focus management with shared state

- Updated `EditableCell` to use `Arc<String>` for the `key` prop to ensure efficient reference handling.
- Added `focused_cell` and `set_focused_cell` signals to manage focus state across components.
- Replaced local focus tracking with a global mechanism to handle input focus changes, improving UX consistency.
- Introduced `NodeRef` for direct input element manipulation, ensuring the focused cell regains focus after state updates.
