Replace the four existing Flathub screenshots with captures from the
1.2.5 build (new logo, new sidebar, refreshed login chrome) and add
three new ones that showcase features worth highlighting on the
Flathub listing:
* enriched-artist-page.png — artist view with editorial data
* hifi-wizard.png — DAC setup wizard
* immersive-line-bed.png — immersive line-bed playback mode
Metainfo manifest is updated in the next commit because Flathub freezes
screenshot URLs by commit SHA, so we need this commit's SHA to land
first.
