fix: batch of collections/i18n/translate-button fixes (v0.53.1)

- Drag-reorder used verticalListSortingStrategy on a multi-column grid,
  which computes wrong transforms for grid reflow — swapped to
  rectSortingStrategy so cards actually animate live while dragging.
- Grip handle was rendered as a sibling of (not a descendant of) the
  `group` element its `group-hover:opacity-100` depended on, so it was
  permanently invisible. Fixed the DOM nesting and made it always
  partially visible instead of hover-only.
- common.edit was missing from both locales (not just French) —
  edit-collection-dialog.tsx was the first caller to hit it.
- Root cause of "generated in my language but Translate still shows":
  generate-meal, meal-plan/generate, and adapt never set recipes.language
  on the row they inserted, so the button's `!recipe.language || ...`
  check always fell back to "show it". Fixed at all three insert sites.
- Translate dialog was entirely hardcoded English (title, description,
  language names, buttons) despite i18n keys already existing for most of
  it — now uses them, plus new translated language-name keys.
- Recipe tags now render on the recipe detail page (previously grid-card
  only).
- Collection header actions converted to icon-only + tooltip, matching
  the recipe page's pattern instead of icon+label buttons.
- Collections list search now also matches recipe titles inside each
  collection, not just the collection's own name/description.
- Explore page links to /collections/explore next to its tabs.
