Watch all six MIDI links from the checklist, including ProPresenter -> Lighting

Browse Source 
Adds Tracks -> Livebox, Tracks -> Studio B and ProPresenter -> Lighting
(read on the ProPresenter Mac over SSH), each with the hold-to-reconnect fix.
coremidi.py now recognises the network MIDI driver on macOS 26.2 too
("AppleMIDIRTPDriver"; 26.5 calls it "AppleMIDINetworkDriver"), which is why
the ProPresenter Mac's session looked empty before.
