v2.26.11: fix APRS map ignoring configured observer position (#193)

Browse Source 
The APRS map initialisation only checked for a live GPS fix, falling
back to the centre of the US (39.8N, 98.6W) when none was available.
It never read the observer position configured in .env via
INTERCEPT_DEFAULT_LAT / INTERCEPT_DEFAULT_LON.

Seed aprsUserLocation from ObserverLocation.getShared() (or the
Jinja-injected defaults) on page load so the map centres on the
user's configured position and distance calculations work without GPS.
