feat: integrate DDMA eligibility into BullMQ queue with persistent session

- Route DDMA eligibility through InProcessQueue (concurrency=1) so it
  queues behind other selenium jobs instead of running concurrently
- New ddmaEligibilityProcessor: starts Python session, polls for OTP/
  completion via socket events, saves PDF and updates patient DB
- Frontend ddma-buton-modal now uses shared app socket + job:update
  pattern (drops private socket connection)
- SeleniumService: upgrade ddma_browser_manager with credential hash
  tracking, anti-detection options, and startup session clearing;
  upgrade DDMA worker with firstName/lastName support, PDF via
  printToPDF, force-logout on credential change; upgrade helpers with
  dual OTP strategy (app API + browser polling); add /clear-ddma-session
  endpoint; reduce fixed sleeps with smart WebDriverWait
