[p2p/lookup] Listen on All IPs for a Peer

[patrick-ogrady]

When a peer updates its IP, we will only accept connections from the latest IP rather than all registered across tracked peer sets:

monorepo/p2p/src/authenticated/lookup/actors/tracker/directory.rs

Lines 232 to 241 in 936dc58

	/// Return all registered IP addresses.
	pub fn registered(&self) -> HashSet<IpAddr> {
	// Using `.allowed()` here excludes any peers that are still connected but no longer
	// part of a peer set (and will be dropped shortly).
	self.peers
	.values()
	.filter(|r| r.allowed(self.allow_private_ips))
	.filter_map(|r| r.socket().map(|s| s.ip()))
	.collect()
	}

We should consider allowing a peer to dial us from any of their tracked IPs (can help with complex end-of-epoch procedures where a peer waits to update their IP until they've exited the epoch ... and generally seems more "correct").

This is not an issue in discovery because we don't filter by IP.
