fix: rebrand Shadboard → CannaManage, staff permissions UX

- Sidebar, footer, bottom-bar-header: replaced 'Shadboard' with 'CannaManage'
- Footer: removed 'Designed by Qualiora' attribution
- Staff permissions: single-column layout, alphabetically sorted by label
- Edit permissions dialog: useEffect syncs state when dialog opens
  (fixes pre-fill not working when controlled externally)
