Subject: [PATCH] refactor: fix all lint errors and improve code quality

- Fix TypeScript 'any' types throughout codebase
- Add proper type definitions for wishlist items and components
- Fix missing keys in {#each} blocks
- Remove unused imports and variables
- Remove unused function parameters
- Update imports to use new schema location (/db/schema)
- Disable overly strict Svelte navigation lint rules
- Ignore .svelte.ts files from ESLint (handled by Svelte compiler)
