fix: non-disruptive env check — drop wifi reload + misleading hop warning

- STA uplink disable now uses uci commit + ip link set wlan0 down instead of
  wifi reload, so the env check never bounces radios/APs/drops monitors
- Removed the wlan0mon 'hop is off' warning: field-verified hop=0 is normal
  (wlan1mon also reports 0 while scanning both bands); the STA/AP pinning
  checks are the real signals
- recon/status drops wlan0_hopping; UI keeps wlan0_sta + wlan0_pinned pills
