Refactor(rename): Simplify rename logic and UI

This commit refactors the app renaming functionality in the `AppDrawerAdapter` for a simpler user experience and cleaner code.

The rename button has been changed from a `TextView` to an `ImageView`, and a cancel `ImageView` has been added. The logic for handling rename actions is now more direct:
- Clicking the save button with an empty text field resets the app name to its default.
- Clicking save with a non-empty field applies the new name.
- A new cancel button allows the user to exit the rename mode without making changes.

This removes the complex `TextWatcher` that previously updated the save button's text (`Rename`/`Reset`/`Cancel`) based on the input, simplifying the view holder's binding logic.
