[Bug] Data list pagination gets stuck on an empty page after deletion

[akramcodez]

Description

In src/commands/data/list.tsx, deleting the last remaining item on the final page of the data list fails to decrement the current page state, leaving the user stranded on an empty, out-of-bounds page.

Environment

• macOS version: N/A
• Apple Silicon: N/A
• Node version: N/A
• Python version: N/A
• Nanotune version: Latest

Steps to Reproduce

1. Open the data list view via nanotune data list.
2. Navigate to the last page (e.g., Page 2/2).
3. Ensure there is only 1 item on this last page.
4. Delete the item using the d hotkey.

Expected Behavior

The UI should automatically navigate back to the previous page (e.g., Page 1/1) since Page 2 no longer exists.

Actual Behavior

The table is empty, and the header reads "Page 2/1". The user is stuck until they manually press the Left arrow key.

Additional Context
