Docs request: How to use the IP allowlist

[sgatewood-da]

• I think we need a versioned doc (e.g. on https://dev.network.canton.global/) describing which IPs get allowlisted to which endpoint
  • e.g. I think I’m currently giving validators access to cometbft, and I’m not actually sure if they are supposed to have that access
• I don’t see this taking a ton of effort, other than maybe answering questions that we really should be asking

More context

• This is a duplicate of this issue within CN's internal repo
• I also had this in our meetings doc and wayne asked I move it here

IEU's comment from the SV doc

• IEU: Agree that we need this
  • Hard to know which IPs to whitelist to which endpoints; need to manage multiple security groups
  • Need documentation showing what should be accessed by / open to whom

Leaked info found:

Validators only need access to:

• Sequencer endpoint
• Scan API

You should also allowlist their VPN to the scan UI
