Social Studio — Calendar view + direct publishing

Social Studio gets a month-grid calendar showing every scheduled post at a glance, and posts approved on the board can now actually go live. Connect the social integrations you use and hit publish — or let the scheduler handle queued posts automatically.

• ›Calendar tab on /studio/social with a full month view, today indicator, prev/next navigation, and a per-day drill-down
• ›Each day cell shows scheduled posts colour-coded by status — draft, scheduled, published, failed — with time and target platforms
• ›Direct publishing from the board — a "publish" button on approved/scheduled/failed cards sends to connected platforms immediately
• ›Automatic publishing for scheduled posts — the system checks every 15 minutes and posts anything that's due
• ›Per-channel outcome tracking — if one platform fails, the others still go out and the failure shows on the card
• ›Supported platforms for text posts: LinkedIn, X, Facebook, Threads, Bluesky. Instagram, YouTube, and TikTok (media-first platforms) coming next
