feat: favorite button on the My Recipes grid; fix mobile overflow in bulk-action bar

- Added a heart toggle to all three recipe-grid views (grid card overlay,
  list row, compact row), hidden while in multi-select mode. Detail page
  already had it; this was the other place it made sense.
- recipes/page.tsx now fetches which of the current page's recipes are
  already favorited and passes it through.
- FavoriteButton gained an optional iconClassName so the unfavorited heart
  reads on a photo overlay (was invisible in light mode against the dark
  backdrop — filled/favorited state was already fine since it's opaque red).
- Fixed the floating bulk-select action bar overflowing both edges of the
  viewport on mobile (screenshotted: centered with no max-width, wider
  than the screen, clipping "Supprimer" on one side and the selected-count
  label on the other). Now caps to viewport width, scrolls horizontally
  as a fallback, and drops button text labels below sm (icon + aria-label
  + tooltip only), matching the icon-row convention used elsewhere.
