feat: TTLock page redesign — sector circles, COM dropdown, DLL diagnostics

- SectorPicker: circles 1–16, click to toggle (blue=selected, gray=not)
- COM port: dropdown populated from agent's serial ports list + refresh button
- Per-workstation buttons: HardDriveDownload (save), Zap (test encoder)
- Workstations without COM port shown as dimmed with amber 'Энкодер не настроен'
- DLL entry point error shown with hint to check TTHotel libs/index.js
- Backend: GET /ttlock/dll-info?workstation_id= → reads TTHotel index.js via agent
- api.ts: added dllInfo() call
