fix: cantaloupe export subprocess cwd points to cantaloupe-downloader project

The subprocess.run for cantaloupe export was using cwd=admin_server_dir,
which meant 'python -m cantaloupe' couldn't find the local cantaloupe module.
Changed cwd to ~/projects/cantaloupe-downloader where the module lives.

Also added scripts/cantaloupe-sync.sh — the 6h cron job wrapper script.
