fix(cmail-setup-finish): verify both Bridge ports and dump status on failure

The "verifying Bridge is listening" check used a regex
`127\.0\.0\.1:(1143|1025)` against `ss -ltn` output. That matches if
*either* port is listening, but the success message claims both are. So
a half-broken Bridge (IMAP up, SMTP down or vice versa) would pass the
check.

I split the check into two greps and report which port is missing.
When the check fails, the script now also prints the last 10 lines of
`systemctl --user status protonmail-bridge` to stderr so the operator
sees the service state immediately instead of being told to go run the
command themselves.
