All paths into sky-cam.conf; install.sh generates systemd units

sky-cam.conf
- Add SCRIPT_DIR (install location) and CAM_NAME (camera/folder name)
- These are the only values that change when deploying to a new machine

install.sh (new)
- Sources sky-cam.conf, generates all systemd .service and .timer units
  with correct ExecStart paths, then enables and starts the timers
- Run once after editing sky-cam.conf; run again if paths change
- Supports --system flag for system-wide install

All .sh scripts + sunrise2mm.py
- No hardcoded paths remain
- script_name=$(basename ...) derivation replaced by $CAM_NAME from conf
- sunrise_video.10s.sh now sources sky-cam.conf for BASE_DIR, CAM_NAME,
  and SCRIPT_DIR (replaces all /home/motion/... references)
- sunrise2mm.py builds video path from BASE_DIR + CAM_NAME in conf

systemd/ template files kept as reference but no longer need editing
