feat: parse admission notes into structured price table

Browse Source 
Parse semi-structured notes text (e.g. "Samstag: Erw. 15 €, Kinder 8 €")
into grouped table rows instead of showing raw text below the table.

- Split notes on sentence boundaries (". " + uppercase), handling
  abbreviations like "Erw." correctly
- Extract "Label: Category Price €" patterns into table groups
- Expand common abbreviations (Erw. → Erwachsene, Erm. → Ermäßigt)
- Guard against "Cat: Price, Cat: Price" format (colons in pricesStr)
- Guard against bare prices after colon (letter-start requirement)
- Graceful fallback to flat table + raw notes when parsing fails
