fix: extract appointmentDate for multi_claim/batch_claim/preauth intents

The classifier prompt only told the AI that appointmentDate applies to
schedule_appointment/claim_only/check_and_claim, so a trailing date like
"all on 6/23/26" was dropped for multi-patient claims even though the
workflow already reads c.appointmentDate for those intents and silently
defaulted to today.

Also add Prisma config/seed scripts and shopping-vendor types/schema updates.
