Loads the full editor payload for one template type: raw override regions (null = inherit), resolved effective content, catalog defaults, theme color, and current settings (enabled, delivery method, logo visibility).

Auth: Both — authentication + an email-template feature check. company_id scoped by an ownership check. Additionally, platform-owned types are forbidden (403) for any non-platform company. (Only the reachable companies differ per role, as above.)

Rate limit: No rate limit.
