Feat/translate fi

[SanteriMoilanen]

Adds Finnish translations for the admin dashboard, following the community translation contribution guide.

Summary

What — What changes are introduced in this PR?

Adds Finnish (fi) as a supported language for the Medusa Admin dashboard:

• packages/admin/dashboard/src/i18n/translations/fi.json — full Finnish translation of en.json
• packages/admin/dashboard/src/i18n/translations/index.ts — registers fi in the translation resources map
• packages/admin/dashboard/src/i18n/languages.ts — adds fi to the language list (display name "Suomi", date_locale from date-fns/locale)
• packages/admin/dashboard/src/i18n/plural-config.json — adds "fi": ["one", "other"] (Finnish uses the same two-form plural rule as English)

Why — Why are these changes relevant or necessary?

Finnish was not yet among the community-translated languages available in the Admin dashboard. This lets Finnish-speaking merchants use the Admin in their native language, following the existing admin translation contribution guide.

How — How have these changes been implemented?

Followed the documented translation contribution flow: copied en.json as the base, translated every string value to Finnish (keeping all keys, interpolation placeholders like {{count}}/{{title}}, and JSX-like tags such as <0>/<LinkComponent> untouched), then wired the new locale into index.ts, languages.ts, and plural-config.json the same way every other language is registered.

Testing — How have these changes been tested, or how can the reviewer test the feature?

• yarn i18n:validate fi.json (run from packages/admin/dashboard) passes — confirms fi.json matches the translation schema and has the correct plural key forms for every pluralized string.
• Verified fi.json has identical key structure to en.json (same leaf keys, no missing/extra entries).
• Verified by native Finnish speaker.

Examples

Not applicable — this is a translation-only change, not a new API or component.

Thanks for the contribution! Initial automated review looks good.

The PR adds a complete Finnish (fi) locale to the Admin dashboard. The translation file is correctly named (fi.json), and spot-checks across multiple sections confirm the values are legitimate Finnish — not copies of English text. The required wiring changes (languages.ts, translations/index.ts, plural-config.json) all follow the established pattern for other languages. Finnish plural forms (["one", "other"]) are correct. A changeset for @medusajs/dashboard at patch level is included. No security issues, performance issues, or bugs were found. PR template is fully filled out.
