Support Locale query parameter on API v2 endpoints (posts, boards, custom fields)

We use the Featurebase API v2 to build a custom feedback portal embedded in our app. Our app supports multiple languages (Dutch, French, English).

Featurebase already supports auto-translation on the hosted public portal, but this functionality is not available via the API. When we fetch posts via GET /posts or GET /posts/:id, content is always returned in the original language (Dutch in our case), regardless of the requesting user's language.

Request: Add a locale query parameter to the following API v2 endpoints:

• GET /posts (list posts)

• GET /posts/:id (get single post)

• GET /boards (list boards)

• GET /custom_fields (list custom fields)
  

When locale is provided (e.g. ?locale=en), the response should return auto-translated titles, content, board names, and custom field labels -- the same translations that are already available on the hosted portal.

Use case: We have a React app with a fully custom Featurebase integration via your API. Our users switch between nl, fr, and en. Currently all Featurebase content appears in Dutch regardless of their language setting. We'd like to leverage the same auto-translation you offer on the portal, but through the API.
