fix(admin-v2): Restore complete admin-v2 application

The admin-v2 application was incomplete in the repository. This commit
restores all missing components:

- Admin pages (76 pages): dashboard, ai, compliance, dsgvo, education,
  infrastructure, communication, development, onboarding, rbac
- SDK pages (45 pages): tom, dsfa, vvt, loeschfristen, einwilligungen,
  vendor-compliance, tom-generator, dsr, and more
- Developer portal (25 pages): API docs, SDK guides, frameworks
- All components, lib files, hooks, and types
- Updated package.json with all dependencies

The issue was caused by incomplete initial repository state - the full
admin-v2 codebase existed in backend/admin-v2 and docs-src/admin-v2
but was never fully synced to the main admin-v2 directory.
