feat(ui): add static news ticker in header cycling every 10 seconds with i18n support [defer to 3.9.0]

[rafacpti23]

This PR implements a static news ticker banner in the dashboard header.

Key changes:

• Adds a static JSON file in public/news/news.json for managing announcements.
• Creates a NewsTicker React component cycling through news items every 10 seconds.
• Supports smooth transition fade animations and a pulsing indicator.
• Fully supports localization (i18n) by rendering translated strings matching the current locale with safe base/english fallbacks.
• Integrates the NewsTicker component in the central section of the global Header.tsx only on the initial/home page.

Review note

No automated review issues were flagged (gemini-code-assist quota was exhausted). The feature adds a static news ticker in the header cycling every 10 seconds with i18n support.

Could you rebase onto the current release branch (release/v3.8.27) to resolve any conflicts? Once rebased, the automated reviewers should be able to process it.

Obrigado pelo empenho, @rafacpti23! 🙏 O componente em si (cleanup de interval/fetch, rel=noopener) está decente, mas no formato atual o PR não pode entrar no produto:

1. Conteúdo promocional embarcado (public/news/news.json): o ticker traz itens fixos apontando para um curso pago (mundoautomaik.com) e um grupo de WhatsApp. Todo deploy do OmniRoute passaria a exibir essa propaganda no header — isso não é apropriado para o produto base.
2. i18n fora do padrão: o projeto usa next-intl com src/i18n/messages/<locale>.json (42 locales) + useTranslations. O PR cria um esquema paralelo (strings num JSON em public/, só pt/en) e ignora 39 idiomas.
3. Sem testes (Rule fix(ci): add environment for npm token access #18).

Se você quiser transformar isso num recurso genérico — um feed de avisos configurável pelo operador (via settings/DB, sem conteúdo promocional fixo), com i18n via src/i18n/messages e testes — ficaria ótimo e reavaliamos com prazer. Deixo o PR aberto para essa reescrita. 🙌

Thanks @rafacpti23 for this! As the title notes ([defer to 3.9.0]), the news ticker is a nice cosmetic addition but out of scope for the v3.8.38 stabilization branch. Leaving it open and queued for the 3.9.0 cycle — no changes needed from you for now. 🙏

Validei este PR contra o tip atual da release/v3.8.38 (sweep /green-prs):

• ✅ typecheck:core limpo
• ✅ ESLint dos arquivos (NewsTicker.tsx, Header.tsx) sem erros/warnings — os reds de Lint/Unit/Integration que apareciam eram de um run antigo (14/06) contra uma base desatualizada, não do código deste PR
• ⚠️ Faltava teste automatizado para código de produção (Hard Rule fix(oauth): prevent connection test from corrupting valid tokens #8 + gate PR Test Policy)

Empurrei para o seu branch um teste (tests/unit/ui/NewsTicker.test.tsx, 6 casos) cobrindo o fallback de i18n (locale exato → idioma base → inglês), a segurança do link externo (rel=noopener/target=_blank) e o render nulo em feed vazio ou falha de fetch. Roda verde no vitest e mantém o PR como seu. Obrigado pela contribuição! 🙌

Obrigado, @rafacpti23! O news ticker está bem feito (i18n via useLocale(), testes incluídos 👍), mas vamos adiar para a 3.9.0 — alguns pontos a ajustar antes:

1. CI UNSTABLE — os checks ainda não estão verdes.
2. Rota locale-prefixada — o pathname === "/home" esconde o ticker em rotas com prefixo de locale (ex.: /en/home, /pt-BR/home). Melhor casar o final do path.
3. setTimeout dentro do setInterval (NewsTicker.tsx ~63-68) não é limpo no unmount — guarde a ref e limpe no cleanup.
4. O conteúdo do news.json está hardcoded — idealmente configurável pelo operador.

Deixo aberto, marcado para 3.9.0. Quando ajustar os itens acima, a gente revisa de novo!

Thanks @rafacpti23! You marked this [defer to 3.9.0] in the title yourself, so I'm honoring that — leaving it open and parked for the 3.9.0 cycle rather than merging into v3.8.44. It'll need a quick rebase and a small regression test for the ticker rotation when it comes up. Appreciate the contribution. 🙏

[diegosouzapw]

Thank you for this, @rafacpti23 — the NewsTicker implementation is genuinely clean: proper client-side cleanup, cascading i18n fallbacks (locale → base → en → pt), graceful null render when there's no news, safe external links, and responsive hiding on small screens. Nice work. 🙌

A header news ticker is a visible product/brand surface, so we're deciding it in the 3.9.0 cycle rather than mid-3.8.x — which is why this carries the [defer to 3.9.0] tag. To keep the PR queue clean, I'm closing this for now and I've opened #6116 to track it for 3.9.0, referencing your implementation as the base.

When the 3.9.0 release branch opens, please re-open a focused PR against it — I'd love to land your version. The only small follow-up noted in the tracking issue is i18n-ing the hardcoded "News" badge label (the item text is already localized). Thanks again for contributing! 🚀
