Vista Cues 1.1.0: a wired-network setting; a sender set by name or off it shows red

The Macs at NA are also on Wi-Fi and the Dante networks, and Bonjour lists each MIDI session once
per network. On 2026-10-20 the Tracks and Companion senders were set to Wi-Fi addresses, so the
lighting MIDI ProdDash hears rode Wi-Fi. With "Wired network" set (This machine; e.g. 10.1.0.0/16,
several with commas), a sender typed as a name or as an address outside it, and a session that
joins us from outside it, turn the admin status line and the tile's sender chip red, naming the
sender. It still joins, so the cues keep showing. Empty (the default) changes nothing; a typo in
the setting fails the module in /admin with a plain message.
