feat(ratings): mix cutoff filter for random flows and home, i18n

Apply the same per-axis star cutoff to random mix (multi-batch fetch until
full), random albums, Hero, and Home hero/discover rows. Prefetch artist and
album ratings via Subsonic when list payloads omit them. Exclude items when
0 < rating ≤ threshold; 0 or missing counts as unrated.

Settings: rating filter description interpolates sidebar menu labels; Russian
strings for custom title bar; short axis labels aligned across locales.
