feat(ui): recipe thumbnail su Select Recipe + fit (object-contain) su Gestione Ricette

- /measure/select: aggiunta miniatura 64×64 accanto al nome ricetta
  (object-contain per mantenere l'immagine intera, non croppata).
  Lo schema backend RecipeSummary esponeva solo id/code/name/active:
  aggiunti image_path e description così la card può rendere thumb
  e sottotitolo.
- /maker/recipes: la miniatura passa da object-cover (crop) a
  object-contain (fit), per visualizzare l'intera immagine della
  ricetta senza tagli.
