Remove a SKU alias

Secret key (server-side only), sent as Authorization: Bearer sk_…. This is the higher API-key tier: it satisfies routes requiring either the pk or sk tier. On pk-level routes no Origin header is required, and any forwarded Origin is ignored. The secret key satisfies the API-key tier only; it does not bypass visitor-token requirements, instance scoping, quotas or metering, or any other route-specific authorization. Routes requiring the sk tier remain secret-key-only, including administrative surfaces such as SKU alias registration, the origin allowlist, usage, and visitor deletion.
