Add Remove Button to Dashboard for Network Configs

[alexanderjcurry]

Please add a remove button to the dashboard network page.

I set DHCP via the dashboard thinking I could undue it, you can't unless you dig deep into the system and manually remove it... You are now left permanently with DHCP being set since the way I understand Talos is that it applies networking in layers, where console-defined networking is stored as platform state and evaluated above the machine configuration. As a result, once platform networking is enabled, it must be explicitly removed or the node reinstalled — editing the machine config alone cannot override it.

The fix is below but for the love of God add a remove button that just deletes the meta file so we do not have to dig deep into the system to get rid of a config we set by the dashboard.

$ talosctl get operatorspecs --namespace=network-config
NODE NAMESPACE TYPE ID VERSION
192.168.3.168 network-config OperatorSpec platform/dhcp4/ens18 1 <------ This was from me setting the DHCP IP in the dashboard (platform set)

$ talosctl get addressspecs
NODE NAMESPACE TYPE ID VERSION
192.168.3.168 network AddressSpec ens18/192.168.3.168/24 2
192.168.3.168 network AddressSpec ens18/192.168.3.50/24 2 <------ This is from my machine config I applied (machine config set)
192.168.3.168 network AddressSpec lo/127.0.0.1/8 2
192.168.3.168 network AddressSpec lo/169.254.116.108/32 2

$ talosctl -n 192.168.3.168 get meta 0x0a <----- This is the meta file that stores me setting DHCP in the dashboard
