feat(tun): expose mihomo tun dns-mode in TUN settings

Support the dns-mode field introduced in mihomo v1.19.33. A
button group below the stack selector offers
Auto/Disabled/Native/Hijack; Auto writes an empty string, which
the core treats as the legacy behavior. Adding dns-mode to
GUI_KEYS makes the value GUI-authoritative once saved, matching
the other TUN dialog fields.
