fix: decrease connection timeout in sonmmon (#1630)

Internals:
We're connecting to a worker we use the full address (eth@ip:port) and shouldn't go through rendezvous\relay, probably, we can use a shorter timeout to obtain the first status quickly. This change also should decrease time to show first sonmmon screen after reboot.
