Coro outbound source IP addresses

Use them to allowlist traffic originating from Coro, including in Microsoft Entra Conditional Access Named Locations.

These are outbound NAT addresses only. Do not use them as destinations for the Coro console, APIs, agents, or other Coro services; use the documented DNS names instead.
