feat: add Armenian flag SVG and update existing flag SVGs

- Added a new SVG file for the Armenian flag (am-1952–1990.svg).
- Updated the existing Armenian flag SVG (am.svg) to use a new structure and color scheme.
- Refactored logo loading logic in App.svelte to reset filters and state when loading a new collection.
- Simplified PNG and JPG download functions in Actions.svelte to directly use collection variable directory.
- Enhanced SVG source fetching in CardFull.svelte to utilize a helper function for image URL generation.
