networkmanager: prompt for the VPN username on import
NetworkManager stores a VPN username as a connection property
(vpn.data["username"]), not a secret, and its SecretAgent only ever
requests secrets -- so it never prompts for the username. Importing an
.ovpn with a bare auth-user-pass therefore produced an unusable connection
with no username, and at connect time the server rejected the (empty) auth.
Capture the username right after import, while nothing is activating:
- New e_networkmanager_vpn_username.{c,h}: a predicate deciding when a
username is needed (by VPN type + connection-type), a single-field dialog,
an async `nmcli connection modify <uuid> +vpn.data username=...` writer
(+vpn.data so the rest of the dict is preserved), and a post-import probe.
- The probe queries only vpn.data (a single line) by connection UUID, which
avoids both the duplicate-name ambiguity and the multi-line ecore_exe
data/exit race; the VPN service type comes from the import type.
- e_networkmanager_import.{c,h}: capture nmcli stdout and report the new
connection's UUID to the done callback.
- e_mod_main.c: trigger the probe on a successful import.
- test_vpn_username.c: standalone unit test for the predicate matrix.
The username stays a property and is never sent as a secret (the openvpn
plugin rejects that); the connect-time dialog remains password-only, like
every other NetworkManager front-end.
