feat: rename DDMA to ClaimMD across selenium service, remove MH/CMSP eligibility feature

Rename ddma_browser_manager/helpers/worker files to claimmd_* naming in
SeleniumService. Remove the MassHealth (MH) and CMSP eligibility-check
feature end to end: buttons and dead placeholder buttons on the insurance
eligibility page, their handlers and auto-trigger wiring, the chatbot's
MassHealth-only manual paste flow, backend routes/queue job types/processors,
and the corresponding Python Selenium worker endpoints. Multi-provider
eligibility checking (DDMA, Delta, Tufts SCO, United SCO, CCA, BCBS MA) and
the Twilio SMS eligibility flow are untouched.
