andreasandClaude Haiku 4.5 2b00157642 Fix RTL8822CE kernel panic on 5GHz AP with VHT
Problem: RTL8822CE driver caused kernel panic (watchdog hard LOCKUP) when
hostapd tried to use VHT 802.11ac with 80MHz channel width on channel 149.

Root cause: Driver/firmware instability with VHT capabilities on this chip.

Solution: Disable VHT, use HT40+ (802.11n) only.
- Removes ieee80211ac (VHT), ieee80211ax (802.11ax), and 80MHz channel width
- Keeps HT40+ with Short GI for reasonable performance
- Stable operation on channel 149 (5745 MHz)

This allows the 5GHz AP to start and beacon without lockup on R5C hardware.

# Put the AP into br0 so Wi-Fi and the wired LAN port share one 10.42.1.0/24 segment.
# hostapd adds the wlan to the bridge after setting AP mode; the bridge itself + its
# wired member + the gateway IP are defined under /etc/systemd/network (2x-van-br0/lan).

# (state=ENABLED means it's actually beaconing) — used to detect a wedged radio that
