feat(ui): disable all photo upload actions for unregistered users

- Updated ImageMethodDialog.vue to accept an isRegistered prop and show "Register to Upload a Photo" message instead of upload UI when not registered.
- Updated AccountViewView.vue to pass isRegistered to ImageMethodDialog and replace all profile photo add/upload buttons with the same message for unregistered users.
- Ensures consistent UX and prevents unregistered users from accessing any photo upload features.
