Drop SSID display from settings, connection pill shows generic "Connected"

Real hardware testing (Pixel 10a) showed NetworkCapabilities.getTransportInfo()
consistently returns a redacted WifiInfo (SSID "<unknown ssid>", masked BSSID)
even for the app's own self-requested WifiNetworkSpecifier network, disproving
this codebase's prior assumption of a self-request exemption from
ACCESS_FINE_LOCATION for that API path (confirmed via native diagnostic
logging cross-checked against `adb shell dumpsys wifi`, which does show and
correctly attribute the true SSID at the OS level). Rather than add a location
permission with a runtime prompt purely for this cosmetic display, the
settings pill now just shows "Connected". Documented as decision 4.24.
