Add radvd to gateway role to advertise Pi as high-preference IPv6
default router using the stable ULA prefix (fd1e:.../64). With
FritzBox also sending RAs, devices end up with ECMP between Pi and
FritzBox. To solve this, add network_ipv6_gateway (Pi's link-local)
as a static route with metric 100 to all managed hosts — beats RA
metric 425, ensuring all IPv6 default traffic goes through Pi.
Fix IPv6 MASQUERADE in gateway-apply-rules:
- Direct mode: add MASQUERADE on end0 (LAN devices use ULA source
addresses not known to FritzBox, so Pi must NAT them)
- FORWARD rules: restrict to RELATED,ESTABLISHED only — previously
the broad ACCEPT rule passed un-NAT'd packets alongside masqueraded
copies, causing duplicate SYNs, conntrack corruption, and RSTs
- MASQUERADE/clear rules: match by interface not by source subnet
(devices may use any source address, not just the ULA prefix)
- VPN mode return traffic: explicitly restrict to wg+→end0 direction
Add network_ipv6_gateway var (optional) to network role NM templates
(ethernet, wifi, bridge) — injects a static IPv6 default route at
metric 100 when set. Add rpi5 static route to FritzBox link-local so
Pi keeps IPv6 after FritzBox RA is disabled.
Force SSH to IPv4 for *.local hosts (AddressFamily inet) — prevents
Ansible from hanging on mDNS returning multiple IPv6 addresses.
Update gateway and pihole READMEs with two-step IPv6 setup process.

Remove static IPv6 support from network role — all hosts use SLAAC
(method=auto). Simplifies NM templates, argument_specs, and resolved.conf.
gateway sysctl accept_ra=2 is now unconditional when gateway_enabled.

This prevents FRITZ!Box from messing up the setup when seeing a new mac
address on the LAN connections (causing it to block the pi or not able
to wake the pve)

Since ipv6 seems to be causing a lot of issues with the new ISP

This migrates away from using the default wpa-supplicant, and use iwd
instead on all the hosts

The pihole lookup DNS queries when the VPN connection is up was slow.
One of the culprits was the quad9 servers were taking long time when
using VPN
The other issue was the previous routing tables that used to work with
the fritzbox (with DHCP) which wasn't fully working was conflicting with
the VPN route tables and causing loops and delays.
Now most of the VPN queries are working fast but some requests are
taking some time, probably due to the VPN trying to check/block ads and
malware!
Also minor fixing to the pre tasks and documentation

The testing was failing because the use of the example files with the
same domain names, resulted in the files and the molecule variable were
being merged and therefore running tasks that would fail on test
(example, setting a fake VPN connection that wouldn't start).
