[Feature Request][Network indicator] Add a GUI toggle to disable an Ethernet connection, like the existing Wi-Fi toggle

[e2jk]

Use case

I connect my personal laptop to a USB-C dock at work. The dock has an Ethernet port wired to the office network, which requires joining a work network I don't want my personal machine on (and isn't guaranteed to even work for a non-corporate device). I only want to stay on the public/guest Wi-Fi.

As soon as the dock's Ethernet link comes up, NetworkManager grabs the default route away from Wi-Fi, and my browser gets redirected to the work network's captive portal — even though Wi-Fi is connected and working fine. The only way I found to stop this is a terminal command (nmcli connection modify "<profile>" connection.autoconnect no), which isn't discoverable for most users and isn't exposed anywhere in the GUI.

Current behavior

The network panel (top-right bar indicator) has an on/off toggle for Wi-Fi, but no equivalent control for a wired connection. There's no way to tell Omarchy "don't use this Ethernet connection" from the UI.

Proposal

When Wi-Fi and Ethernet are both connected/available, show a toggle for each — the same way Wi-Fi has one today — so a wired connection can be explicitly switched off (and back on) from the network panel, without needing the terminal.

Prior search

I searched the tracker before filing. The closest thing I found was #5436 ("Deprioritize iPhone USB tethering below Wi-Fi"), but that's about automatically de-prioritizing USB tethering via routing metrics — it doesn't add a manual UI control, and it's specific to phone tethering rather than general wired/dock Ethernet. This request is for an explicit, user-facing on/off switch for any Ethernet connection, matching the existing Wi-Fi toggle's UX.
