chore(web): drop the double cast from the useSessionRef test fixture

Browse source 
Addresses Copilot's review on #2152. The client stand-in was
`({ tag }) as unknown as InspectorClient` — a double cast with no
justification, which AGENTS.md rejects.

`Object.create(InspectorClient.prototype)` gives a real prototype chain
without running the constructor, so it needs only a single cast and still
drags in no transport or environment. The tag went with it: every
assertion compares identity, and `Object.create` already returns a
distinct object per call.
