refactor(mobile): ask these call sites for a request port, not a whole client

The migration widened seven files from `Pick<RpcClient, 'sendRequest'>` to the
full `RpcClient` for no reason: a bound operation's `request` takes
`UnvalidatedRpcRequestPort`, which is structurally that same single member.
Name the port instead, so the signature says what each function actually needs
and a caller holding only a port still satisfies it.
