feat: Tufts SCO claim automation, Claim All button, fee schedule updates

- Add full Tufts SCO claim Selenium worker (steps 1-8): login with OTP
  support, member search, Create Claim, fill form, attach files, submit,
  extract claim number and save confirmation PDF
- Fix DentaQuest browser manager to preserve device trust token on startup
  (only clear cookies, not LocalStorage/IndexedDB) so OTP is only needed
  once for both eligibility and Tufts claim
- Fix Tufts SCO claim route credential lookup key (TUFTS_SCO not TuftsSCO)
- Add Tufts SCO and United/DentalHub entries to fee schedule update route
- Add "Claim All" button that auto-routes to the correct claim handler
  based on the Insurance Type dropdown value
- Add fee schedule JSON files for DDMA, Tufts SCO, and United/DentalHub
