feat: add CCA claim submission with Selenium automation

- Add CCA claim submit Selenium worker (login, fill form, attach docs, submit, capture dashboard PDF)
- Add CCA fee schedule (procedureCodesMH.json renamed, procedureCodesCCA.json added with D6010)
- Add backend route /api/claims/cca-claim, processor, and Selenium client
- Wire CCA claim handler in claims-page with job tracking and PDF preview popup
- Add insurance type dropdown in claim form (same options as eligibility page)
- Auto-populate insurance type from patient.insuranceProvider in claim form and patient edit form
- Map fee schedule by insurance type in Map Price button and combo buttons
- Fix CCA login speed (remove fixed sleeps, use readyState check)
- Fix CCA claim DOB format bug (was sending MM-DD-YYYY, now sends YYYY-MM-DD)
- Fix npiProviderId not saved for CCA claims
- Change Add Service → CCA Claim button (blue), MH → MH Claim
