feat(furni-editor): compact permissions + upgraded meta chips

- Merge the lone Inventory permission (allowInventoryStack) into the
  Gameplay group, dropping the separate Inventory header+row to save
  vertical space.
- Rework the header meta row: ID/Sprite as label+monospace-value pills,
  'in use' tinted green with a dot when placed instances exist (grey at
  0), 'Unsaved' as an amber pill with a dot.
