fix: replace any types with proper types across codebase

Replace ~100 `any` usages with proper types: use existing interfaces
(RecipeModelType, BriefRecipeType, IPayment, etc.), Record<string, unknown>
for dynamic objects, unknown for catch clauses with proper narrowing,
and inline types for callbacks. Remaining `any` types are in Svelte
components and cases where mongoose document mutation requires casts.
