* i18n: complete the Japanese catalog and check it like the other languages
Japanese lacked 105 strings that other languages already have: the
open-link and open-email confirmations, DPI settings, the script sandbox
note, XFA form notes, signing, table and page-mode settings, and the
Contributors / Models statistics. Each now has a Japanese row, so the
interface no longer falls back to English for them.
`japanese_covers_ui_literals` joins the French, German, Russian and
Simplified Chinese checks: every `tl!("…")` literal in the UI source needs
a Japanese row. ATTRIBUTION.toml carries the catalog's new SHA-256.
