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

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.

+## [2.26.11] - 2026-03-14
+
+### Fixed
+- **APRS map ignores configured observer position** — The APRS map always fell back to the centre of the US (39.8°N, 98.6°W) when no live GPS fix was available, ignoring the observer position configured in `.env` (`INTERCEPT_DEFAULT_LAT` / `INTERCEPT_DEFAULT_LON`). Now seeds the APRS user location from the shared observer location on page load, so the map centres correctly and distance calculations work. (#193)

+---
+
+## [2.26.10] - 2026-03-14
+
+### Fixed
+- **APRS stop timeout and inverted SDR device status** — The APRS stop endpoint terminated two processes sequentially (up to 4s) while the frontend timed out at 2.2s, causing console errors and the SDR status panel to show stale state (active after stop, idle during use). Now releases the SDR device immediately and terminates processes in a background thread so the response returns instantly. (#194)

 ## [2.26.9] - 2026-03-14
