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.

<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Most devices:</strong> Ship with a small 915/868 MHz stubby antenna</li>
<li><strong style="color: var(--text-primary);">Works for:</strong> Short range (&lt; 1 km) urban, indoor testing</li>
<li><strong style="color: var(--text-primary);">Upgrade:</strong> Replace with tuned antenna for 5&ndash;20x range improvement</li>

<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Whip antenna:</strong> ~$8&ndash;15, tuned 915/868 MHz, SMA connector</li>
<li><strong style="color: var(--text-primary);">Ground plane:</strong> 8.2 cm vertical + 4 radials (915 MHz) on SMA</li>
<li><strong style="color: var(--text-primary);">Yagi:</strong> ~$15&ndash;30, directional, great for point-to-point links</li>
<li><strong style="color: var(--text-primary);">Collinear:</strong> ~$20&ndash;40, omnidirectional with higher gain (~5&ndash;8 dBi)</li>

<li><strong style="color: var(--text-primary);">Height wins:</strong> Elevating antenna 10m can double or triple range</li>
<li><strong style="color: var(--text-primary);">Line of sight:</strong> LoRa works best with clear LOS to other nodes</li>
<li><strong style="color: var(--text-primary);">Connector:</strong> Most devices use SMA or RP-SMA &mdash; check before buying</li>
