## Prints the address AppFlow would connect to, resolved through the same
## ServerInfo (built-in default + res://serverlist.txt). Used by
## script/live_smoke_test.sh so the port precheck can never drift from the
## client connect target. Never opens a connection or reads credentials.
##
## env: MT_SERVER_INDEX (default 0), MT_SERVER_CHANNEL (default: the first
## channel listed for that server, matching the login screen default).
## stdout: one line "SERVER_ADDRESS {json}". exit 2 when unresolvable.
