French translation V2 (#10301)

This PR improves the French translations already submitted.
- Corrected missing translations.
- Ensured the JSON structure matches the English version.
- Verified consistency across all keys.

The file is very large and it's hard to make sure everything is right.

The previous Similar PR is [Add french trad in i18n translations #9885](https://github.com/medusajs/medusa/pull/9885)

Let me know if additional changes are needed! Happy to help :)
