fix(ui): trail GPX export — guard against USB-app collision

Browse Source 
The Wio L1 DualSerialInterface multiplexes BLE + USB on the same frame
protocol: when BLE is connected, the USB receive path is ignored, so we
can safely push raw GPX bytes to USB without confusing the companion
app. When BLE is *not* connected the app is talking over USB itself —
the dump would land mid-frame and the app would parse garbage.

Block the export when hasConnection() (BLE link to the app) is false
and show "Connect BLE or disconnect app". When it's true the dump runs
and the confirm alert reads "GPX N B over USB" so the user knows which
pipe to read from.
