feat: generate a complete themed meal from a collection (v0.52.0)

New "Generate meal" button on any owned collection — pick a theme (free
text) and 2-6 courses (starter/main/side/dessert/drink), one generateObject
call produces a coherent recipe per course (shared cuisine/style, matching
flavors across courses) and all of them get saved as real recipes and
added to that collection in one action.

Follows the meal-plan generation route's established pattern: single
withAiQuota charge for the whole generation, then a pre-flight loop
charging the tier's recipe limit once per generated recipe (rolled back
on a partial breach) before the insert transaction runs. Recipes are
tagged with their course name for later filtering; visibility defaults to
private like every other AI-generated recipe.
