Fix rtl_433 bias-t flag and add TSCM enhancements

Browse Source 
- Fix bias-t option in rtl_433 for RTL-SDR and HackRF:
  - rtl_433's -T flag is for timeout, not bias-t
  - RTL-SDR: Use :biast=1 suffix on device string
  - HackRF: Use bias_t=1 in SoapySDR device string
- Add "Listen (FM/AM)" buttons to TSCM RF signal details
  - Switches to Listening Post mode and tunes to frequency
- Fix device detail header padding to prevent protocol badge
  overlapping with close button
