fix: set platform name on every entity create — patients/appts/calls/etc no longer "Untitled"

Audited all 23 sidecar create-mutation call sites; 7 were missing the
top-level data.name field that the platform uses as record title:

- caller-resolution.service.ts createPatient — full name from first/last
- maint.controller.ts createPatient (backfill-lead-patient-links) — same
- widget.service.ts createPatient (chat path + booking path) — full name
- widget.service.ts createAppointment — "<Patient> — <date>"
- worklist/missed-queue.service.ts createCall — "Missed — <phone>"
- rules-engine/actions/escalate.action.ts createPerformanceAlert —
  "<agent>: <message> (<value>)"
- supervisor/agent-history.service.ts createAgentEvent / createAgentSession

Cosmetic only — the app fetches fullName/agentName for display, so
end users never saw "Untitled". Fixes platform-side admin browsing.
