TikTok: getUserProfile, getUserVideos, createVideo (PULL_FROM_URL),
getVideoStatus via Content Posting API v2. Full multi-tenant credential
isolation and audit logging on write operations.
Snapchat: getMe (Login Kit), getAdAccounts (Marketing API). createSnap
throws with a clear explanation that Creative Kit is mobile-only — no
server-side posting API exists.
Platform type, validPlatforms list, and /api/connections endpoint all
updated to include tiktok and snapchat. Architecture diagram updated.
