feat(readarr): refresh and rescan a Readarr author and expose the command on the CLI

Posts the RefreshAuthor command to the command endpoint with the author ID, queueing a metadata refresh and a disk scan for that author. The response is returned verbatim and no app state is mutated.

Adds the refresh subcommand group to the Readarr CLI.
