Refactor PWA caching and image generation scripts

- Updated `generate-pwa-cache-list.js` to include images directory and remove duplicate file entries.
- Refactored `generate-svg-variants.js` to utilize collections from a centralized source and renamed generation directory variable.
- Modified `update-data.js` to align with new directory structure for images and variants, ensuring proper paths are used.
- Adjusted `collections.js` to standardize directory naming for variants.
- Enhanced Svelte components (`Actions.svelte`, `CardFull.svelte`, `CardMiddle.svelte`, `CardSmall.svelte`, `CardTiny.svelte`) to utilize context for collection management, simplifying image URL generation.
