fix(FR-2502): allow admin to see all vfolders across projects/domains (#6525)

Resolves #6524 (FR-2502)

## Summary
- `AdminVFolderNodeListPage` was restricted to the current domain via `scope_id: domain:${domainName}`, so superadmin could only see folders owned by themselves and not vfolders created by other users
- Remove `scope_id` from the admin query (all three `vfolder_nodes` calls: main list, active count, deleted count) so superadmin sees all vfolders across projects/domains
- Matches the existing pattern in `AdminComputeSessionListPage` which intentionally omits `scope_id` for the same reason
- Drop the now-unused `useCurrentDomainValue` import and `domainName` local

## Stack
Depends on #6467 (FR-2476), which adds `permission: read_attribute` to the same queries. The permission fix alone does not make other users' folders visible; removing the domain scope is also required.

## Test plan
- [ ] `/admin-data` page shows vfolders owned by other users (across all projects/domains)
- [ ] Active and deleted folder tab counts reflect all vfolders
- [ ] Existing filters (name/status/type/permission/usage mode) still work

## Verification
```
=== Relay: PASS ===
=== Lint: PASS ===
=== Format: PASS ===
=== TypeScript: PASS ===
=== ALL PASS ===
