M3: chat widget, owner dashboard, super-admin panel

- Embeddable vanilla-JS chat widget (one script tag + tenant public key):
  WebSocket, resumable sessions (24h localStorage token), honeypot + per-IP
  and per-message rate limits, Bosnian UI (§7)
- Session auth (bcrypt + signed cookies), owner accounts + super-admins,
  admin impersonation ('otvori kao salon', §11)
- Owner dashboard (§10, Bosnian): requests with same actions as email,
  call/chat history with transcripts, usage bar; settings for profile,
  working hours (manual + LLM paste-to-parse), services CRUD + 'Zalijepi
  cjenovnik' LLM import with review step, scheduling (Google OAuth free/busy
  read-only + calendar mappings + buffers, partner status), telephony
  (forwarding MMI codes per operator, ring group, worker SIP creds + QR),
  agent voice/price-mode/notes + widget snippet, notifications/SMS templates
- Super-admin panel (§11): tenant CRUD incl. plan/minutes/paid-until,
  partner API config (encrypted secrets), number/SIM registry + assignment,
  connectivity test (live availability + dry-run push), versioned prompt
  template editor with publish/rollback, playground, usage overview, health
- Fixes: WAL + busy_timeout for sqlite tests, no awaits in WS disconnect
  path (deadlock), template publish autoflush bug
- 76 tests green (incl. widget WS e2e booking flow); dashboard, widget and
  admin verified live in a browser against Postgres
