Validate post content

Dry-run the full post validation pipeline without publishing. Catches issues like missing media for Instagram/TikTok/YouTube, hashtag limits, invalid thread formats, Facebook Reel requirements, and character limit violations. Accepts the same body as POST /v1/posts. Does NOT validate accounts, process media, or track usage. This is content-only validation. Returns errors for failures and warnings for near-limit content (>90% of character limit).
