feat: add Deltains claim submission flow

Adds a full "Deltains Claim" button next to Delta MA Claim, mirroring
the DDMA claim flow across frontend, backend queue/routes, and a new
Selenium worker. Reuses the existing Deltains eligibility login/OTP
code and was iteratively wired against the live portal (patient roster
search, per-service-line fields, tooth number/surface selects, review
and submit). Also fixes chatbot/insurance-alias carrier recognition so
"deltains" resolves correctly instead of falling back to MassHealth.
