LazyImage on Safari (#5626)

This pull request improves the lazy loading behavior and caching
strategy for images in the `LazyImage.vue` component. The most
significant changes are focused on optimizing image rendering and
resource management, as well as improving code clarity.

**Lazy loading behavior improvements:**

* Changed the `<img>` element to render only when `cachedSrc` is
available, ensuring that images are not displayed before they are ready.
* Updated watchers in `LazyImage.vue` to use clearer variable names
(`shouldLoadVal` instead of `shouldLoad`) for better readability and
maintainability.

**Caching strategy enhancement:**

* Modified the `fetch` call in `mediaCacheService.ts` to use `{ cache:
'force-cache' }`, which leverages the browser's cache more aggressively
when loading media, potentially improving performance and reducing
network requests.
