feat(i18n): MaintainershipBanner acknowledges AI-drafted safety-critical content

Updates the banner notice across all six locales to be explicit that
the AI-initial locales (FR / ES / IT / PL) are AI-drafted including
the Coach's safety-critical instructions, and that automated
validation guards them in CI. The CTA reframes from "help out" to
"report on GitHub" so users with a regression know the
contribution path is bug reporting, not editorial rewrites.

Pins the new wording in the banner test so a future copy regression
cannot quietly soften the disclosure. Banner gating (renders only on
non-maintained locales, SSR-safe) and the GitHub-issue CTA target
URL remain unchanged from W9e.
