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. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
