- 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 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
