fix(api): de-prioritize rotting sxyprn/trafficdeposit thumbnails

Browse source 
sxyprn thumbnails are time-signed on trafficdeposit CDN and ROT — the signed asset
404s after ~weeks and can't be re-signed/refreshed server-side (bug 2026-06-10,
~15k sxyprn-only scenes showed broken thumbs). In the light-list slim-thumbnail pick,
prefer a thumbnail from any non-trafficdeposit source; fall back to sxyprn only when
it's the scene's sole thumbnail (recent ones still load; dead ones now render a clean
placeholder client-side instead of a broken image).
