The ucode migration wrote "basic_rate" into the wpa_supplicant network
block, but that is not a valid wpa_supplicant network field, causing:
Line 15: unknown network field 'basic_rate'.
failed to parse network block.
Map UCI basic_rate to the correct wpa_supplicant fields, matching the
behavior of the legacy shell script (hostapd.sh):
- mesh mode: mesh_basic_rates (space-separated, 100 kb/s units)
- sta/adhoc: rates (comma-separated Mbps)
