feat: AI-powered eligibility detection from Copy Agent screenshots

Adds an "AI Detect & Check Eligibility" action to the Copy Agent page that
sends captured screenshots to Claude to extract Member ID/DOB, then opens
the chatbot's eligibility confirm step pre-filled with the result.

- POST /api/ai/detect-eligibility-info: Claude vision extraction of
  Member ID/DOB from uploaded screenshots.
- POST /api/patients/create-temp: auto-creates a placeholder "PID-<id>"
  patient (matched by insuranceId+dob) when no patient is selected, so
  screenshots can be saved immediately; the real eligibility check later
  rewrites the patient's name and Cloud Storage folder automatically via
  the existing createOrUpdatePatientByInsuranceId matching logic.
- Chatbot: Member ID/DOB on the confirm card are now editable (MM/DD/YYYY),
  with edits synced back to the patient record before the check runs.
- Fixed a useEffect ordering bug on the insurance-status page that could
  silently clear a chatbot-prefilled Member ID/DOB before the auto-trigger
  effect ran, preventing the eligibility check from ever starting.
- Added a local-disk-only screenshot backup (apps/Backend/uploads/
  screenshot-backups/) for debugging, not exposed anywhere in the UI.
