A firewall restart flushes the fail2ban chains. The new handler restarts
fail2ban only if it is active; it does nothing if fail2ban is stopped or
not installed.

Shared variables (and fw_ext_interfaces / fw_local_interfaces) can now be
overridden for IPv6 via <name>_v6. extract-fw-host-vars.py emits these
overrides when the IPv4 and IPv6 configs differ, instead of a warning.
Add host_vars for nd.warenform.de, oolm-shop.oopen.de, web-01.oopen.de
and web0.warenform.de (fw_manage_config: true).

- Update firewall scripts and shared conf files from firewall/ipt-server
(HTTP connection limits, IPv6 TCP MSS clamping, ban_ipv6_mask,
mattermost TCP fallback, rename 'stansard_*' -> 'standard_*').
- New role variables: fw_set_max_new_http_conn_per_ip_per_second,
fw_max_http_new_conn_per_ip_per_second, fw_set_max_concurrent_http_conn_per_ip,
fw_max_concurrent_http_conn_per_ip, fw_set_max_new_http_conn_per_second,
fw_max_new_http_conn_per_second, fw_throttle_tcp6_mss_for_https,
fw_tcp6_mss_for_https_val, fw_mm_tcp_ports_in, fw_ban_ipv6_mask.
- Split fw_blocked_ips into fw_blocked_ips_v4 / fw_blocked_ips_v6 and
rename it in host_vars accordingly.
- Restart firewall when scripts or shared conf files change.
- extract-fw-host-vars.py: map new variables, normalize '${var}' and renamed
bash variables, fall back to IPv6 for shared variables and warn if IPv4
and IPv6 values differ.
- README.md / MIGRATION.md: document host_vars naming
(<short-hostname>-ipt-server.yml) and new variables.

- Created a new configuration file for ga-al-gw-neu with detailed network interface settings and routing rules.
- Updated existing configurations for ga-al-gw, ga-gh-gw, ga-nh-gw, ga-st-gw-ersatz, ga-st-gw, and ga-st-mail to include additional DNS servers and correct domain controller IPs.
- Disabled systemd-resolved for ga-st-mail to prevent conflicts with DNS settings.
- Added user definitions and SSH key configurations for default users across multiple hosts.
