feat: AI claim queue auto-return + D1120 age warning

- claims-page: after auto-submit closes the form, automatically navigate
  back to /appointments when an AI claim queue is pending resume, eliminating
  the manual navigation delay between appointments
- internal-chat-workflow: warn and block claim when D1120 (child prophy) is
  requested for a patient aged 14+ — recommend D1110 (adult prophy) instead,
  and advise manual claim if user insists on D1120
