feat: improve CCA preauth cell filling, implants category, preauth no recording

- Selenium: bulletproof Wait→Click→Clear→Type→Verify for tooth, billed amt cells
- Selenium: fix billed amt to click td[23] (correct column) to trigger edit mode
- Selenium: skip tentative date (auto-filled by page after tooth entry)
- Frontend: add Implants category with Implant/Abut/Crown, Fixture, Abutment, Crown buttons (D6010/D6057/D6058)
- Frontend: pdf-preview-modal renders PNG screenshots as <img> instead of PDF iframe
- Backend: CCA preauth route creates claim record if none exists
- Backend: CCA preauth processor saves authNumber into claimNumber column after submission
