Activate a regulation on this tenant
Records tenant intent to surface the given regulation on the dashboard. Writes one row to meshqu.tenant_regulations and one audit_log entry. Does NOT create, scaffold, or tag any policies — tagging policies with regulatory_refs is a separate step (services-led during pilot onboarding in v1).
Authorizations
MeshQu API key passed as a bearer token: Authorization: Bearer mqu_…. Mint one in the console (Settings → API keys).
Tenant UUID for multi-tenant isolation. Required on all authenticated routes — validated before authentication (middleware/tenant.ts), so a missing or non-UUID header returns 400 (MISSING_TENANT_ID / INVALID_TENANT_ID) before the API key is checked.
