"""Add the tiktok_credentials table — the TikTok inbox-upload poster.

Singleton row (mirrors ``x_credentials``, migration 059) holding the
Fernet-encrypted OAuth2 secrets: client_key/client_secret (static) plus
access_token/refresh_token (rotate on refresh — ``TikTokCredentialsService.
update_tokens`` is the narrower write for that path). Additive and inert
until real TikTok credentials are set.
