Use get_image_url() for building media_image in media_item

[antonk-dev]

Currently if image not remotely accessible mass_queue#return_image_or_none don't try to resolve it url using proxy_id field.

Music assistant client have get_image_url API that could resolve image to MA image proxy path that will be accessible from same network.

Additional benefit - from first sight it supports resizing, so maybe using smaller size images for queue items could save some traffic / make things load even faster.

Some context: #42 (comment)

Actually it looks like it already used (although not via API) in download image code - download_single_image_from_image_data.

Can that part be used for building URL without download option? (to avoid downloading and encoding on server side) - maybe as separate config option in queue? (like resolve_proxy_id_urls).

Although that causing mix of http / https - it looks like working in Chrome (although with warning Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure element '<URL>'. This request was not upgraded to HTTPS because its URL's host is an IP address.).

Moreover that perhaps could be solved on MA side if reverse proxy will also cover MA host + domain name (with https preffix) will be used as "Base URL" in MA settings - making this proxied URLs accessible even without mixing HTTP / HTTPS

Regarding HTTP / HTTPS mix - if MA behind reverse proxy and use correct Base URL (with https + domain name) - everything going via HTTPS. But even in default configuration (http on 8095 + IP address) - Chrome allowed to have mix (although with some warnings in logs)

I mentioned return_image_or_none here because it is deepest point.

But actual path (one of) could looks like
process_queue_images -> _process_queue_images -> process_image_single_item -> find_image -> find_image_from_metadata -> return_image_or_none
