fix(topbar): restore full right cluster per user preference

User explicitly: "Руководство · dev · 19a3731b · ☀️🌙🖥 · RU EN · zimin.an · ↩
это оставь". Revert MR !81 cluster-minimization — diagnostic info нужна
для prod debugging.

Restored:
- Docs link (/docs/) — opens admin docs portal
- VersionBadge (channel + commit short SHA) — shows local/dev/v1.x.x · hash
- LanguageSwitch (dual RU | EN radio) — keeps both visible vs single-toggle
- (ThemeSwitch + AuthBadge остаются как были)
