feat: supervisor fixes — settings disabled cards, column toggle fix, hold SSE, campaign edit disabled

- SectionCard: added disabled prop (muted, non-clickable, no arrow)
- Settings hub: Clinics, Doctors, Team, Telephony, AI, Widget cards disabled
- Campaigns: edit button disabled
- Missed calls + Call recordings: column toggle blank page fixed (key-based
  Table remount forces clean React Aria collection on column change)
- Live monitor: replaced 5s polling with SSE stream for real-time active
  call updates (new/hold/unhold/disconnect reflected instantly)
