Reset one tenant config key
Clears the request tenant’s override for a fenced config key, returning it to the catalog default. Idempotent: resetting a key with no override is a successful no-op. An off-catalog key is 404. Returns 204 No Content. RBAC: config:write; the actor and tenant are always derived from the validated request identity, never a path or payload value.
