Subject: [PATCH] feat: enable IPv6 on 1panel-network by default (#12202)

When creating the 1panel-network Docker bridge, IPv6 was explicitly
disabled (EnableIPv6: new(bool) = pointer to false). Users wanting
IPv6 had to manually recreate the network.

Now 1panel-network is created with dual-stack support:
- IPv4: 172.18.0.0/16 (gateway 172.18.0.1)
- IPv6: fd00:1panel::/64 (gateway fd00:1panel::1)

Uses ULA (Unique Local Address) range which doesn't require public
IPv6 allocation and works for internal container-to-container
communication.

Note: Existing installations are not affected - this only applies when
the network is first created. To upgrade, stop all containers, delete
1panel-network, and restart 1Panel.

Closes #12202
