feat: batch eligibility, batch claim, and batch check+claim from AI chat

- Add batch_eligibility, batch_claim, and batch_check_and_claim intents
  to AI classifier so multiple patients can be processed one by one
- Add queue processing on insurance-status and claims pages to auto-start
  the next patient after each check/claim completes
- Make patient schema firstName, lastName, phone optional so patients can
  be created with just member ID + DOB from eligibility checks
- Cancel buttons now preserve chat history instead of clearing it
- Patient-found card shows Check Eligibility, Eligibility & Appointment
  Today, and Cancel buttons
- Claim service date asks user to pick between latest appointment and
  today when they differ
- Login page subtitle styled with animated gradient
