fix(packaging): run service as root for packet capture
- Change systemd service to run as root instead of ja4sentinel user
- Remove user/group creation from RPM spec (%pre script)
- Update %post to set root:root ownership on directories
- Adjust security hardening for root execution (ProtectSystem=strict)
- Add ReadWritePaths for writable directories

Fixes: systemd error 'Failed at step USER spawning /usr/bin/ja4sentinel: No such process'
