Add antenna quick reference guides to all mode sidebar panels

Browse Source 
Each SDR mode now includes frequency-specific antenna guidance:
- Pager: VHF/UHF dipole info for 153/929 MHz bands
- 433 MHz Sensors: quarter-wave ground plane for ISM band
- Utility Meters: 912 MHz stock antenna tips and upgrades
- APRS: 2m band dipole and commercial options for 144.39 MHz
- SSTV: V-dipole for ISS reception at 145.800 MHz
- AIS: marine VHF antenna for 162 MHz vessel tracking
- Listening Post: wideband discone recommendation with band table
- Meshtastic: LoRa 915/868 MHz antenna upgrades and placement
- ADS-B: 1090 MHz collinear, commercial options, LNA/placement

Each guide includes antenna type, element lengths, placement tips,
and a quick reference table with key specs for the mode.
