Warn users when socket_org is missing and upload is skipped

When an API key lacks the socket-basics:read scope, the dashboard
config cannot be loaded and socket_org is not auto-discovered.
Previously this caused a silent skip of result uploads with only
a debug-level log message.

This change upgrades the log level to WARNING and provides
actionable guidance: set SOCKET_ORG environment variable to
enable uploads without requiring the socket-basics:read scope.
