Every message another catalog knows is now in the German, Spanish, French,
Japanese and Ukrainian catalogs (plain and formats): 927 plain and 34 format
messages added or translated, following each catalog's existing
terminology, register and punctuation; placeholders unchanged. Menu paths
inside translated text use → (the UI font has no ▸). Values identical to
English are kept only where correct (ISO, Display P3, words spelled the same,
language self-names, placeholder-only formats).
Measured: de 97%, es 98%, fr 97%, ja 99%, uk 99% of 2,398 catalog messages.
pt-BR, ru, zh-hans and zh-hant are left to their open PRs. Agent-made
translations: native-speaker review welcome.
Also fixes the Rust 1.99 clippy lint chunks_exact_to_as_chunks in
pipeline/spots.rs that fails `cargo xtask ci` on main.
