feat: recipe type (dish/drink) for better cocktail handling (v0.31.0)

Add recipes.recipeType enum (dish|drink, default dish). Recipe form
now shows a Type selector and hides food-only fields for drinks
(prep/cook time, difficulty, batch-cook toggle) instead of forcing
every cocktail through meal-oriented UI. Detail page skips the
meal/drink pairing suggestion buttons on drink recipes (pairing a
drink with a drink doesn't make sense). Recipes list gains a Type
filter facet alongside difficulty/batch-cook.

Scoped deliberately narrow per investigation: no ABV/glass-type/
garnish structured fields, no meal-plan schema changes, and the
existing AI drink-pairing-suggestion feature (ephemeral, never saved
as a recipe) is left as-is rather than wired into recipe creation —
those suggestions are wine/beer/spirit recommendations without
ingredients/steps, not really recipes to save.
