Use domainId for both deletion methods.

The updated documentation covers primary and satellite domains, but both @param tags still expose satelliteDomainId. Typedoc will show a satellite-only name for methods that also accept primary-domain IDs. Rename the method parameters and delegation argument to domainId so the public documentation matches the documented contract.

Also applies to: 85-85

In `@packages/backend/src/api/endpoints/DomainApi.ts` at line 76, Rename the
deletion-method parameters currently documented as satelliteDomainId to
domainId, including the corresponding delegation argument, so both primary and
satellite domain IDs use the same public name and Typedoc matches the contract.
