- AccountView: remove hardcoded @ prefix so handle matches what share dialog expects
- documents store: set is_shared=true optimistically after successful share so badge shows without refetch
- GET /api/documents/{id}: allow recipients of an active share to view the document (was returning 404 for non-owners)
- ShareModal: move Share button to its own full-width row so it no longer overflows the input area

- Add Username row (@handle) to Account information section in AccountView.vue
- Add Handle column (th + td with @prefix) to users table in AdminUsersTab.vue
- Both use existing data already present in API responses (no backend changes)
