Keep plugin labels, spacing, and save controls stable in edit mode

[chriskmnds]

Overview

Edit mode should keep plugin rows and editing controls visually stable inside the sidebar.

This covers four related layout issues:

• Keep plugin labels on a single line in edit mode.
• Make Save and Cancel buttons sticky at the bottom in edit mode.
• Reduce plugin item padding from 16px to 8px to align with sidebar icons.
• Prevent the Save button from overflowing when the label changes to "Saving...".

Behavior

• Plugin labels should stay on one line and truncate when needed.
• Save and Cancel should stay reachable at the bottom of the sidebar while editing.
• Plugin item padding should align with the rest of the sidebar icon rhythm.
• The Save button should not grow outside the sidebar when showing a saving state.

Why

Customize mode should feel calm and predictable. Wrapping labels, shifting controls, misaligned icons, or overflowing buttons make the editing state feel unstable and harder to trust.
