+/**
+ * Per-tenant OpenClaw image override (admin-only).
+ *
+ * Why admin-only: customers cannot pick OpenClaw versions. This
+ * exists so the platform team can A/B-test new releases on specific
+ * tenants without rolling them out fleet-wide. The endpoint enforces
+ * `user.isPlatform`; even owners of the tenant's org cannot use it.
+ *
+ * PATCH body shapes:
+ *   - { tag: "2026.4.22" } → use this tag
+ *   - { tag: "" } or empty body → clear override (revert to platform
+ *     default)
+ *
+ * Tag-only by design — see operator notes for rationale.
