Non-root users cannot write to /var/log. Move all log files to /home/joseph (/tmp by default) so the container works when running with custom UID/GID permissions. Changes: - speedtest.log: /var/log/ → /home/joseph/ - cron.log: /var/log/ → /home/joseph/ - Added fallback for speedtest-cli.json copy (handles both root and non-root cases)
