feat(rbac): human labels + descriptions for all 50 permissions

- Add Permissions::permissionLabels() mapping every slug to a
  human-readable RO label (e.g. 'clients.view_all' → 'Vezi toți
  clienții').
- RoleResource permission checkboxes now show translated labels
  as titles + technical slug as description (so admins see both
  the meaning and the key).
- PermissionOverridesRelationManager Select 'permission_id' now
  shows 'Human label (technical.slug)' format, plus helper text
  explaining GRANT/DENY. Same format on the display column.
- +57 translations (50 permission labels in RU/EN + role page
  supporting keys + module labels).

All 306 tests pass.
