Refine Data Connection Layer: error handling, reconnection, write failures, health reporting

Browse Source 
Add connection lifecycle (fixed-interval auto-reconnect, immediate bad quality on
disconnect, transparent re-subscribe), synchronous write failure errors to scripts,
periodic tag path resolution retry, and enhanced health reporting with tag resolution
counts. Update cross-references in Health Monitoring and Site Runtime.
