ProjectKey onMouseDown now triggers _syncFromSource + _refreshKeys so
clicking a relay always picks up source config changes. Added console
logs to notifyRelays and _refreshKeys for diagnosing sync issues.

When ProjectSource widgets (url, project, file, sequence_number)
change, all ProjectKey nodes referencing that source now re-sync
and refresh their key dropdown immediately.
