- Fetch live ISS position from Open Notify API (primary)
- Fallback to "Where The ISS At" API if primary fails
- Remove dependency on potentially outdated local TLE data
- Calculate observer elevation/azimuth using spherical geometry
- Both APIs are free and don't require authentication
This fixes the issue where the ISS position was incorrect due to
the local TLE data being almost a year out of date.

- Add /sstv/iss-position endpoint that calculates ISS position directly
- Update JS to use new endpoint instead of /satellite/position
- Returns lat, lon, altitude, and optionally elevation/azimuth from observer

passes directly using skyfield within the sstv route.
