CmdPal Dock visual bugfixes (#45871)

This PR fixes the following bugs and iprovements:

- The scroll forward/backward glyphs were clipped
- The `Show labels` settings is redundant as those can be set
individually, and actually messes with that setting. Therefore, removed
from the Settings UI.
- Minor string changes
- The 'Filter commands' box is hidden when right clicking the Dock to
customize it.
