feat: MH eligibility & history, CMSP eligibility & history & remaining

- Add MH Eligibility & History button: runs full MH eligibility flow then
  clicks member ID → service history, prints both PDFs via CDP, opens
  dual side-by-side PDF modal (eligibility auto-downloads, history does not)
- Add CMSP Eligibility & History & Remaining button: same flow plus
  navigates back to member details, clicks View Accumulator, prints
  accumulator PDF via CDP; opens 3-panel side-by-side PDF modal
- Generalize DualPdfPreviewModal to accept panels[] array (works for 2 or 3 PDFs)
- Auto-download eligibility PDF via direct API URL to avoid Chrome Safe
  Browsing pause on blob: URL downloads
- New backend processors, job types, and routes for both flows
- New Python Selenium workers with stable CSS selectors (ng-bind, href*)
