fix(cli/status): use descriptors() for device count in daemon mode

discovery.lcd_devices / led_devices are always empty through TrccProxy
because live device objects don't travel over the wire. Both Trcc and
TrccProxy expose lcd_descriptors() / led_descriptors() which do the
right thing in both in-process and daemon-proxy mode.

Fixes 'No devices connected.' in `trcc status` when daemon holds USB.
