feat: add native firewalld support (#1388)

Browse Source 
## Summary

- Add native firewalld support for RHEL/Fedora/CentOS systems
- When firewalld is active, use `firewall-cmd --permanent` instead of
raw iptables
- Rules persist across `firewall-cmd --reload`
- Fall back to iptables when firewalld is not active
- Add `After=firewalld.service` to iptables systemd unit for safety

## Changes

**Install:** Detect firewalld, use `firewall-cmd` to add port,
masquerade, and rich rules. Fall back to iptables if inactive.

**Uninstall:** Detect which method was used and clean up accordingly.

**Tests:** Add `fedora-42-firewalld` CI test with firewalld enabled.

**Q:** What syctl and iptables changes are made by the script?
**Q:** What sysctl and firewall changes are made by the script?
**A:** Iptables rules are saved at `/etc/iptables/add-openvpn-rules.sh` and `/etc/iptables/rm-openvpn-rules.sh`. They are managed by the service `/etc/systemd/system/iptables-openvpn.service`
**A:** If firewalld is active, the script uses `firewall-cmd --permanent` to configure port, masquerade, and rich rules. Otherwise, iptables rules are saved at `/etc/iptables/add-openvpn-rules.sh` and `/etc/iptables/rm-openvpn-rules.sh`, managed by `/etc/systemd/system/iptables-openvpn.service`.
Sysctl options are at `/etc/sysctl.d/99-openvpn.conf`
