feat(firefox): allow plain-HTTP loopback for VPN SSO callbacks
LibreWolf 149+ hardens beyond arkenfox by force-upgrading loopback to HTTPS
(dom.security.https_only_mode.upgrade_local=true) and enabling LNA blocking
of public->loopback redirects. Both break snx-rs / Forticlient / generic
VPN SAML callbacks that land on http://127.0.0.1:<port>/<token>.
Restore stock Firefox / arkenfox loopback behaviour. arkenfox 1245 leaves
upgrade_local intentionally commented out and does not touch network.lna.*,
so this brings us in line with arkenfox rather than weaker than it.
Refs: LibreWolf issues #2954 (Forticlient SSO broken in 149), #2962
(HTTPS-Only Mode locked in 149.0.2-1, reverted in 149.0.2-2).
