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.

Marine VHF band (162 MHz) &mdash; stock SDR antenna will NOT work well

<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Element length:</strong> ~46 cm each (quarter-wave at 162 MHz)</li>

<li><strong style="color: var(--text-primary);">Orientation:</strong> Vertical (AIS is vertically polarized)</li>

<strong style="color: var(--accent-cyan); font-size: 12px;">Commercial Options</strong>
<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Marine VHF whip:</strong> ~$20&ndash;50, designed for 156&ndash;163 MHz band</li>
<li><strong style="color: var(--text-primary);">Discone:</strong> ~$30&ndash;50, wideband coverage including marine VHF</li>
<li><strong style="color: var(--text-primary);">Collinear:</strong> Higher gain (~6 dBi), best for coastal monitoring</li>

<strong style="color: var(--accent-cyan); font-size: 12px;">Placement Tips</strong>
<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Height is critical:</strong> AIS is line-of-sight. Roof or mast mount is ideal</li>
<li><strong style="color: var(--text-primary);">Range:</strong> At 10m height, expect ~25 NM (46 km) range over water</li>
<li><strong style="color: var(--text-primary);">LNA:</strong> Nooelec Lana or similar broadband LNA, mount at antenna</li>
<li><strong style="color: var(--text-primary);">Coax:</strong> Keep cable short. RG-58 loses ~4 dB per 10m at 162 MHz</li>
