[Feat] Add Translate Content based on langage

Description

Hello,
If we are using a language other than English, it would be good to add auto-translation of titles and descriptions into user language.
Best regards

Problem it solves

The translation of the interface improves accessibility in the user's language. However, if we do not translate the content, a non-English user cannot use it, and the interface translation becomes useless.

It allows adding sources in other languages (Russian, Arabic, Chinese) without worrying about the language, as the content is translated automatically to users.

Sure, will handle, as long as you are paying for the tokens 😂

It's not necessary to use an LLM here ;).

Of course, it's possible to use a light, locally hosted LLM — or a paid one — to do the translation job.

Another solution would be to use a classic library like Argos Translate: https://github.com/argosopentech/argos-translate

Note: PR #2260 from @lspassos1 implements dynamic content translation and is currently in review. That PR covers news panel, country brief, and market brief translation. Once that lands, this issue would be largely addressed.

For broader content: the browser's native Translation API (Chrome 131+) handles client-side translation at zero API cost. Worth tracking as a progressive enhancement. @koala73 — close this once #2260 merges, or keep open for remaining untranslated surfaces?
