Subject: [PATCH] fix: Preserve station-specific URLs when updating map state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix URL persistence for station routes (e.g., /w5isp)
- Update handle_url_update to maintain callsign in path
- Modify tracking events to use consistent URL structure
- Prevent unwanted redirects from /callsign to /

URLs now correctly persist as /w5isp?lat=...&lng=...&z=... instead
of redirecting to root with query parameters.
