Better error for connect/shell on connection failure #980
Description
EDIT I realized it was due to a connectivity issue with my VPN. Ideally the CLI would return a more helpful error in this situation. I've updated the title accordingly
I've encountered an issue where the connect and shell commands immediately error
❯ pscale connect load_testing main
Secure connection to database load_testing and branch main is established!.
Local address to connect your application: 127.0.0.1:3306 (press ctrl-c to quit)
Error: unimplemented: unary response has zero messages
❯ pscale shell load_testing main
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:54288' (61)
Error: unimplemented: unary response has zero messages
I can see the database so I don't think it's an auth issue
❯ pscale database show load_testing

Hi @cooperbenson-qz, I'd like to take a stab at this. The plan is to detect proxy connectivity errors in connect.go and shell.go and wrap them with actionable guidance (network/VPN/firewall hints) instead of surfacing the raw "unimplemented: unary response has zero messages". Does that approach work?
