fix: recipe card badge placement, missing tooltips, untranslated label

- Batch-cook indicator moved from next to the title into the icon row
  alongside favorite/visibility (all three now get a tooltip, matching
  the existing favorite-button pattern).
- Favorite button's tooltip text was hardcoded English ("Save"/
  "Saved") instead of using the translation keys already used for its
  aria-label.
- Shortened the batch-cook generate dialog's "Generating…" label
  (fr.json edited by user) — the long text was the real cause of the
  modal overlap, not the dialog structure.
