As seen in the applets (pop-os/cosmic-applets#1453 and pop-os/cosmic-applets#1392), this PR migrates the hand-rolled NetworkManager backend in cosmic-settings with nmrs.

Specifically, we switch the networking pages to use nmrs 3.4.0 for NetworkManager state, device lists, Wi-Fi operations, VPN imports/activation, and secret-agent handling.

This PR also removes the old cosmic-settings-network-manager-subscription crate, drops the direct dbus-settings NetworkManager dependencies, and deletes the unused nmcli VPN helper. I kept nm-connection-editor for profile creation/editing where the UI still depends on it since it's not very conducive to switch everything, obviously.

I also carry Wi-Fi security metadata through the password flow so SAE/WPA3 personal networks can be activated with SAE key management, and make failed/cancelled auth attempts clear pending connection state

This does not build locally. It looks like cosmic-protocols uses an older version of bitflags causing a conflict.

cargo build --release

error: failed to select a version for `bitflags`.
    ... required by package `nmrs v3.4.0`
    ... which satisfies dependency `nmrs = "^3.4.0"` (locked to 3.4.0) of package `cosmic-settings v1.0.12 (/mnt/extra/git/extern-repos/cosmic-settings/cosmic-settings)`
versions that meet the requirements `^2.13.0` are: 2.13.0

all possible versions conflict with previously selected packages.

  previously selected package `bitflags v2.12.1`
    ... which satisfies dependency `bitflags = "^2.9"` (locked to 2.12.1) of package `cosmic-protocols v0.1.0 (https://github.com/pop-os/cosmic-protocols//?rev=d0e95be#d0e95be2)`
    ... which satisfies git dependency `cosmic-protocols` (locked to 0.1.0) of package `cosmic-settings v1.0.12 (/mnt/extra/git/extern-repos/cosmic-settings/cosmic-settings)`

failed to select a version for `bitflags` which could resolve this conflict

@jklgrasso This happened on applets too, and was the case for log. Should be all good now, sorry about that.

Everything is working as I expect it to. Networking and otherwise. Could you create the PRs for cosmic-applets & cosmic-protocols to do cargo updates? Once those are merged, you can revert the change to the lock file, and all should be good here.

@jklgrasso pop-os/cosmic-applets#1453 in applets is pending review right now. pop-os/cosmic-protocols#81 Is open on protocols

pop-os/cosmic-applets#1453 is merged

Didn't build due to the lock file. It now matches the master branch and builds locally. CI will start building this again in an hour or so.

Perhaps the regression tests should also include importing VPN configurations & testing VPNs after import. This PR may have broken WireGuard configuration import.
