fix: P2 defect batch + context-panel edit takeover

Layout (P1-adjacent):
- context-panel switches to an edit-only layout when editingAppointment
  is set. Previously AppointmentForm rendered inline BELOW the AI panel,
  crushing the AI area into a ~2-line strip that made the returning-
  patient summary + quick actions unusable. Edit view gets full height
  with a "Back to context" button.

P2s:
- Remove Attempted sub-tab from Missed Calls worklist (Pending only).
- Add CALL_DROPPED disposition option + propagate through every
  per-disposition Record<CallDisposition,...> map (incoming-call-card,
  call-log, call-history, agent-detail, patient-360).
- Block SLA-gaming on unanswered calls: Book Appt / Enquiry / Transfer
  buttons on active-call-card are disabled until the call reaches the
  answered state (wasAnsweredRef). The disposition filter was already
  in place; this closes the upstream entry.
- Data labels on performance charts: my-performance bar chart shows
  value on top of each bar; donut shows {d}% slice labels; team-
  performance day trend line shows per-point values.
