Fix RF scanning and add status feedback

Browse Source 
- Remove requirement for sdr_device to be set before RF scanning
- Add RTL-SDR device detection check with rtl_test before scanning
- Lower signal detection threshold from -50dBm to -70dBm
- Lower noise floor threshold from 15dB to 10dB above noise
- Add rf_status event for frontend feedback when RF unavailable
- Show status message in RF panel explaining why scanning isn't working
- Add CSS styling for status messages
- Reset RF status message when sweep starts
