refactor: reorganize components into domain subfolders and replace relative imports

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.
