Wi-Fi scan shows **** signal for every network and no frequency

[eliasbakken]

Found testing v1.1.0-RC8-2-g23a2bb6 on A8 s/n 0498 (rtw88 dongle).

A scan returns 9 networks, from a very close AP to faint neighbours. Every one shows the same signal, and frequency is always empty:

{"frequency":"","signal":"****","flags":"psk","SSID":"The Merlins"}
{"frequency":"","signal":"****","flags":"psk","SSID":"Kraakeslottet"}
... all nine "****"

The dropdown therefore reads Kraakeslottet **** for everything.

Why

iwctl station wlan0 get-networks prints signal as four asterisks and marks the unfilled ones with an ANSI colour. wifi-scan strips the colour codes first (sed $'s/\x1b\[[0-9;]*m//g'), so every network comes out as ****. Nothing fills frequency.

Suggested direction

Count the uncoloured stars before stripping, or read RSSI another way (iwctl station wlan0 get-bsses, or iw dev wlan0 scan dump for dBm and frequency). The client already has signalBars() for dBm.

Fixed in #158 (merged as d611c55), commit 6418b88. iwctl prints four stars for every network and draws the unlit ones in grey, so stripping the colour first made everything read ****. The grey stars are dropped first. AccessPoint.frequency is gone as well - iwctl's list has no frequency and nothing ever filled it.

Checked on A8 0498: a scan of 9 networks now reports signals from **** down to *.
