Separate CP admin panel into independent Vite project at /cp/

- New /cp/ Vite project with own package.json, Dockerfile, tailwind config
- Migrated CpLoginPage, CpLayout, AdminDashboard → cp/src/ (self-contained)
- cp/src/lib/utils.ts has only what CP needs (cn, PLAN_LABELS, PLAN_COLORS)
- cp/src/data/mockData.ts has Hotel/User types and mock data
- cp/ builds to nginx static container (hotelsync-cp)
- docker-compose.yml: added cp service
- nginx: added cp.hotelsync.ru → hotelsync-cp:80 (SSL block ready for certbot)
- deploy.yml: builds hotelsync-cp:latest and restarts container on push
- Cleaned src/App.tsx: removed IS_CP branch, CpLoginPage/CpLayout/AdminDashboard imports
