Add LATITUDE/LONGITUDE to conf; sunrise.py reads coords from conf

sunrise.py now reads LATITUDE, LONGITUDE, and TIMEZONE from sky-cam.conf
instead of hardcoded values, using the same pathlib-based pattern as
sunrise2mm.py.  sky-cam.conf gains a comprehensive header with manual
systemd setup instructions and a full script map for future reference.
