fix(wio-tracker-l2): USB power detection works - charge bolt, Power row, GPS hint

Browse Source 
- The AW35615 USB-C controller (FUSB302-style registers, ID 0x91) only
  reports VBUSOK with its measure block on; POWER resets to bandgap only,
  so isExternalPowered() was always false. Board init turns it on
- Status bar shows a charge bolt on the cable, Diagnostics > Live has a
  Power row, the GPS screen notes that charging disturbs GPS, and the
  low-battery warning is skipped on USB as intended
- Roadmap: USB detection closed; GPS indoors still worse than the L1
  even on battery, left open for later
