feat(clients): hide disabled inbounds in the client form selector

The attach-inbounds select in the client add/edit modal listed every inbound, so panels with many disabled inbounds had to scroll past dead entries. InboundOption now carries the inbound's enable flag and the form drops disabled inbounds from the options, keeping ones the client is already attached to so edit mode still renders existing assignments.

Closes #5645
