feat: add list and compact view modes to recipes page

Grid was the only layout. Add a view-mode toggle (grid/list/compact)
persisted to localStorage:
- List: thumbnail + description + inline metadata, one per row
- Compact: dense single-line rows (thumb, title, servings/time/
  difficulty/date/visibility) for scanning large libraries
Selection mode and bulk actions work identically across all three.

Also fixes a real bug hit while wiring this up: "recipe.visibility"
was defined twice in the messages files — once as a flat string
("Visibility", used as the bulk-actions dropdown label) and once as
the {private,unlisted,public} label object. The object silently won
in JSON, so t("visibility") resolved to an object and next-intl threw
INSUFFICIENT_PATH the moment you opened that dropdown. Renamed the
flat one to visibilityMenuLabel.
