Deluan bc16cafb91 fix(artwork): convert animated GIF covers in the background
Resized animated GIF covers were converted to animated WebP by ffmpeg inside
the image request, bound to its 10s timeout. On slow CPUs large GIFs never
finished: ffmpeg was killed, nothing was cached, and every request repeated
the work. With ffmpeg 5.1 the conversion also failed mid-stream when reading
the GIF from a pipe, after the stream was already handed to the client, so
there was no fallback.

Requests now get a static stand-in right away, served with no-store and no
validators, while the conversion runs in the background. A single
process-wide slot bounds these conversions, since they outlive the request
throttle; when it is busy nothing is queued and a later request retries.
The result, or a static fallback if ffmpeg fails, is cached under the same
key. ffmpeg output is now buffered so mid-stream failures fall back to a
static resize. The file cache gains cache.Transient for loader results that
must be served but not stored. Without an available cache, conversion stays
inline.
