Kelsi 2d5b29c77c perf(ui): decode the login background off the main thread ...

The auth screen decoded its background on the frame it first appeared: a
1408x768 PNG in a 2.4MB file, which is 2.4MB of zlib inflate plus the GPU
upload, measured at ~190ms. Start the decode on a worker when the screen
first renders and upload on whichever frame it lands; the existing
descriptor-set guard already skips drawing the background until then, so
the screen simply appears without it for a moment.

The GPU half stays on the main thread, since that is where it has to be —
loadBackgroundImage becomes uploadBackgroundImage and takes pixels the
worker already decoded.

Honest note on value: this is a static screen, so the hitch was hard to
perceive. The loading screen decodes its own image the same way and is
left alone, being a screen that is already a wait.
