pjsip show transports was checked once, immediately after "core show version" first responded — but res_pjsip can take a moment longer to finish binding its transports, so the check would sometimes read an empty transport list and print "NOT LOADED" even though transport-tls came up correctly a second later (confirmed live: TLS SIP traffic on 5061 in the container logs right after the misleading banner). Poll for up to 10s instead of checking once, matching the existing core-show-version wait pattern further up the same script.
