fix: teach AI to recognize recement and fix missing service date in column claim

Add "recement" example to LLM classifier so it spreads across multiple
teeth (recement #5, #3 → two D2920 entries). Add "today" to the AI
column claim message so the LLM sets appointmentDate instead of asking
"Which service date?"
