Pinterest: expose alt_text on pin creation

Feature Request

Pinterest's POST /v5/pins supports alt_text (500 chars). Please add an altText key to Pinterest platformSpecificData on posts_create_post and posts_update_post. Alt text is an accessibility + Pinterest SEO field; every pin published via Zernio currently lands without it, and Pinterest's own account-quality tooling flags the gap.

    This works today, we shipped per-image alt text across platforms on 22 May 2026. Set altText on the media item (mediaItems[].altText, or platforms[].customMedia[].altText if you want a Pinterest-only value) on both POST /v1/posts and PUT /v1/posts/{postId}.

    For Pinterest we send it as the Pin's top-level alt_text on creation and trim it to Pinterest's 500 character cap. One deliberate difference from your request: it lives on the media item rather than in platformSpecificData, because alt text belongs to a specific image and the same value then flows to Instagram, Facebook, Threads, X, LinkedIn and Bluesky in one place.
