pass in unresolved name for use as servername in ws_connect

[emlowe]

Taking a look at old issue [#17923] - aiohttp has supported passing server_hostname into ws_connect for a few releases.

This PR will always pass in server_hostname even if it's an IP address, which may be harmless but I'm not sure and might need some adjustment to only pass in things that look like FQDNs.

I'm not clear on how to test this, but it should work, but only for those hosts listed using FQDNs in the config. Note that P2P node discovery only deals in IPs, so this cannot work in that case.

This uses the so-called ugly way from the bug but I choose this as it keeps everything else the same.

Note

Add optional server_hostname to outbound ws connections and pass unresolved host as SNI/Host header when dialing configured peers.

• Networking / Outbound connections:
  • ChiaServer.start_client(...) adds server_hostname: str | None param.
  • Propagate SNI/Host to aiohttp by setting server_hostname and headers={"Host": server_hostname} in ws_connect when provided.
  • Service._connect_peers_task_handler: pass the original unresolved hostname (unresolved.host) to start_client(..., server_hostname=...) for configured peers.
