fix(openwrt): TollGate apk-native install for OpenWrt 25.x

- WISP wizard: step-by-step flow for WiFi, DHCP, masquerade config
- WAN status: expose lan_ip, dhcp_start/limit, masq, sta_state, wifi_log
- wifi_scan: detect CCMP as WPA2 (psk2) so association succeeds
- opkg: PkgManager enum — detect apk-native mode when opkg not in repos
- tollgate: apk-native install path using manual ipk extraction
- arch detection: read DISTRIB_ARCH from /etc/openwrt_release; normalise
  bare mipsel/mips from uname -m to mipsel_24kc/mips_24kc
- install_ipk: install binutils via apk when ar not in BusyBox
- install_ipk: wget --no-check-certificate for routers without CA bundle
- install_ipk: ar fallback to tar -xzf for non-standard ipk formats
- install_ipk: 5MB overlay space check with clear user-facing error
- middleware: allow "Not enough flash/space" errors through sanitizer
