Consolidate duplicate recipe API routes into a single
api/[recipeLang=recipeLang]/ structure. Both /api/recipes/ and
/api/rezepte/ URLs continue to work via the param matcher. Shared
read endpoints now serve both languages with caching for both.
Also: remove dead code (5 unused components, cookie.js) and the
redundant cron-execute recurring payment route.
Move components from flat src/lib/components/ into recipes/, faith/, and
cospend/ subdirectories. Replace ~144 relative imports across API routes
and lib files with $models, $utils, $types, and $lib aliases. Add $types
alias to svelte.config.js. Remove unused EditRecipe.svelte.
