fix: auto-price CDT codes and fix crown/recement code mismatches

- Auto-fill service line price when a recognized CDT code is typed
  (e.g. D2740), instead of requiring a separate "Map Price" click
- Fix chatbot preauth prefill using an empty DOB for price lookup,
  causing age-tiered codes (D2740) to price as $0
- Re-apply fee-schedule pricing with the loaded patient DOB before
  MassHealth preauth auto-submit
- Add a "Recement Crown" (D2920) combo button distinct from "Crown"
  (D2740) to avoid picking the wrong code/price
- Fix AI note parsing to prioritize "recement" over "crown" regardless
  of word order or tooth-number format (e.g. "#7 crown recement")
