Subject: [PATCH] Add PostGIS extension check to Reitti update_script

Automatically enable PostGIS extension on existing installations if missing.
Checks if extension is already enabled before attempting to create it.

Fixes existing Reitti installations that were created before PostGIS was
added to the initial setup (commit b6312b87d).

Users no longer need to manually run 'CREATE EXTENSION postgis;'
