Updated client config controller to reference updated script name

ref TryGhost/Ghost#24985

The admin-x-activitypub script has been renamed to just activitypub so the client config endpoint should be updated to reflect this change

[coderabbitai]

Walkthrough

The backend-driven frontend client identifier was renamed from "admin-x-activitypub" to "activitypub". The change updates emitted JSON client fields and the constructed CDN URL to reference the "activitypub" bundle. No control flow, version derivation, or error handling logic was modified. An ADR document was updated to reflect the same renaming.

src/**/*.ts: Never use direct string comparisons for ActivityPub IDs; use SHA256 hash-based lookups instead
Use Result helper functions (isError, getError, getValue) and avoid destructuring Result values directly
Awilix uses CLASSIC injection: constructor parameter names must match their registration names
Define routes using decorators rather than direct registration
Prefer immutable entities that emit domain events over mutable entities with dirty flags
Use structured error objects with context in Result types instead of string literals
Prefer class-based handlers with dependency injection over function factories
