Why this endpoint

POST /api/posts and PUT /api/posts/{id} accept a platforms[] array where each entry has a social_account_id and a content_type. The valid content_type values depend on the platform: linkedin_post for LinkedIn, x_post for X, instagram_feed / instagram_reel / instagram_story for Instagram, etc. This endpoint exposes the catalog so clients can build correct payloads without hard-coding the matrix.
