MikroTik: add vlan5 interface, bridge VLAN entry (ether3 tagged),
IP 192.168.5.1/24, IPv6 from-pool, DHCP pool/server/network,
firewall rules allowing IoT internet-only (IPv4 and IPv6),
DNS input from vlan5.
OpenWrt: add switch VLAN 5 (WAN+CPU tagged), br-iot bridge on
eth0.5, iot interface, iot firewall zone (forward ACCEPT,
input REJECT).
Also remove ensure_order from all non-firewall api_modify tasks
as RouterOS does not support move on those paths.
Add community.openwrt collection, dlink host to inventory,
openwrt role with system/network/firewall tasks, and two
playbooks: dlink-init.yml for one-time bootstrap from factory
IP, and openwrt.yml for ongoing idempotent configuration.
Network: MGMT untagged + LAN (vlan2) tagged on WAN port trunk
to MikroTik ether3. Firewall zones replace factory WAN/LAN
with mgmt (input ACCEPT) and lan (forward ACCEPT, AP mode).
