feat: redesign Manage tab to match reference layout

- Add Customization group: User Interface (CUI), Tool Palettes (large),
  Import, Export, Edit Aliases dropdown (small)
- Add Cleanup group: Find Non-Purgeable Items (large), Purge, Overkill, Audit (small)
- Add 8 new SVG icons for all new commands
