- Clienți: noi în perioadă + lead-uri pe sursă
Selector perioadă: azi / săptămâna / luna / luna trecută / anul

═══ Faza 4: Central provisioning ═══
- CoolifyClient service (Coolify v4 REST API wrapper)
- CompanyProvisioner: creează Company + admin user + roles + adaugă
  subdomeniul în Coolify FQDN + trigger redeploy automat
- CreateCompany page override → folosește provisioner, returnează
  notificare cu credentialele admin
- Form CompanyResource extins cu admin_name/email/password (vizibil doar create)
- Action 'Suspendă' / 'Activează' pe table cu confirmation

Env vars necesare în Coolify pentru provisioning auto:
  COOLIFY_API_URL=http://65.21.20.141:8000
  COOLIFY_API_TOKEN=<token>
  COOLIFY_APP_UUID=g13hlrpd5g44zxl5af3ktio2

═══ Faza 5: PWA + branding ═══
- Route /manifest.json dinamic per tenant (nume, theme color, icons)
- Route /sw.js — service worker minimal (cache shell + static)
- TenantPanelProvider renderHook HEAD_END — link manifest + theme-color
  + apple-mobile-web-app meta
- TenantPanelProvider renderHook BODY_END — registrare service worker
