feat(readarr): add the edit author handler

Handles the multi-step edit prompt covering monitored, monitor new
items, quality profile, metadata profile, path, tags, and confirmation.

The prompt can be opened from either the author list or the author
details view, so the originating block is threaded through to the
sub-block pushes and Esc returns to the view the user came from.
