fix: UnitedDH pre-auth number extraction, service lines saved, RCT combo buttons

- Pre-auth step9: scan all table cells alphanumeric-first (A0260616190876 format),
  URL extraction, body scan fallback with debug logging
- Pre-auth route: save service lines (totalBilled) when creating PREAUTH claim record
  so claim page shows correct billed amount after selecting patient
- Pre-auth processor: read pdf_path fallback alongside pdf_url from Selenium result
- UnitedDH/SCO workers: billing entity selection via direct paymentGroupId click,
  Summit Dental Care first with fallback, Escape to close dropdown
- Pre-auth form: remove Other Insurance step (not present on pre-auth page),
  file upload direct to hidden input without button click
- Pre-auth step8: JS click + Submit Authorization in XPath, Continue via [last()] + JS click
- RCT combo buttons added (pre-auth form only): RCT Ant/Post/Crown, PreM/Post/Crown,
  Mol/Post/Crown; claim form excludes these three combos
