Refactor logo image handling across components

- Introduced utility functions to determine the base directory and image URL for logos based on their collection.
- Updated `Actions.svelte`, `CardFull.svelte`, `CardMiddle.svelte`, `CardSmall.svelte`, and `CardTiny.svelte` to use the new utility functions for generating image paths.
- Ensured that the correct image format (SVG, PNG, JPG) is used based on the logo's properties and active color sets.
