feat: SSE-driven worklist + agent call history split + remove SOURCE column

Worklist:
- SSE stream replaces 30s poll — EventSource on /api/supervisor/worklist/stream
  triggers immediate fetchWorklist() on missed-call events
- Toast notification: 'Missed Call — {name} — needs callback'
- No polling fallback — SSE is the source of truth

Call History split by role:
- Agent: 'My Call History' — own calls only (matched by agent relation
  or chain-parsed agentName), missed calls excluded (they belong on
  the Call Desk queue), no Agent/Recording/SLA columns, phone clickable
  via PhoneActionCell instead of separate Call button
- Supervisor: 'Call History' — all calls, Agent + Recording columns visible

Worklist panel:
- SOURCE/BRANCH column removed from display (data stays on row)
