feat: disposition modal, persistent top bar, pagination, QA fixes

- DispositionModal: single modal for all call endings. Dismissable (agent can resume call).
  Agent clicks End → modal → select reason → hangup + dispose. Caller disconnects → same modal.
- One call screen: CallWidget stripped to ringing notification + auto-redirect to Call Desk.
- Persistent top bar in AppShell: agent status toggle + network indicator on all pages.
- Network indicator always visible (Connected/Unstable/No connection).
- Pagination: Untitled UI PaginationCardDefault on Call History + Appointments (20/page).
- Pinned table headers/footers: sticky column headers, scrollable body, pinned pagination.
  Applied to Call Desk worklist, Call History, Appointments, Call Recordings, Missed Calls.
- "Patient" → "Caller" column label in Call History.
- Offline → Ready toggle enabled.
- Profile status dot reflects Ozonetel state.
- NavAccountCard: popover placement top, View Profile + Account Settings restored.
- WIP pages for /profile and /account-settings.
- Enquiry form PHONE_INQUIRY → PHONE enum fix.
- Force Ready / View Profile / Account Settings removed then restored properly.
