Add NestJS endpoints the admin panel org UI was calling (all returning 404):
- GET/POST /admin/orgs — list and create organizations
- GET /admin/orgs/:id — org detail with tenants and orgAdmins
- POST /admin/orgs/:id/admins — create OrgAdmin with hashed password
- PATCH /admin/tenants/:id/org — assign/unassign tenant from org
Also ship the member login page and sidebar fix from the previous session:
- Move /my/login to /member-login to break infinite redirect loop
- Add /member-login to PUBLIC_PATHS in sidebar so it is not intercepted
