The signal handler was intercepting SIGINT but not exiting, causing
the application to continue running. Now re-raises KeyboardInterrupt

The UK range 0x400000-0x43FFFF was the entire UK allocation, not just
military - this incorrectly flagged civilian airlines like EasyJet
(EZY callsign) as military aircraft.
Fixed ranges:
- Removed broad UK range, kept only RAF sub-range 0x43C000-0x43CFFF
- Narrowed France range to actual military 0x3F4000-0x3F7FFF
- Fixed Germany to correct Luftwaffe range 0x3D0000-0x3DFFFF
- Fixed typo in US range (0xADFFFFF -> 0xADFFFF)

The /killall endpoint was not resetting the ADS-B tracking state:
- Added dump1090 to the list of processes to kill
- Reset adsb_process to None
- Reset adsb_using_service flag to False
This fixes the "ADS-B tracking already active" error after using
kill all processes and trying to start tracking again.

The previous logic split the track whenever longitude jumped by more
than 180°, which could happen in cases other than actual antimeridian
crossings, causing gaps in the middle of the orbit track.
New logic only splits when one longitude is > 90° and the other is
< -90°, which specifically identifies crossings of the ±180° line.
Also changed segment minimum from 2 to 1 point to preserve all data.

- Keep trackLine (visible pass trajectory) when drawing orbit track
- Make visible pass line solid (weight 4, full opacity) vs orbit track
(dashed, weight 2, 60% opacity) for clear visual distinction
- Only fit bounds on initial pass selection, not periodic updates
- Prevents map from re-zooming every 5 seconds

The orbit track was being added correctly but wasn't visible because
the map was zoomed to the pass ground track (a small arc). Now the map
fits bounds to include the full orbit track plus observer location
after adding the orbit layer.
Also removed debug console.log statements.

Bug: Both files were fetching orbit data for the dropdown-selected
satellite instead of the satellite from the selected pass.
Fixes:
- satellite_dashboard.html: updateRealTimePositions() now uses
passes[selectedPass].satellite instead of selectedSatellite
- index.html: updateRealTimePosition() now ensures the selected
pass's satellite is included in the position request, and added
includeTrack: true to get orbit data
