MIRTH-2883: Added time zone capabilities to timestamp columns for PostgreSQL and Oracle. The custom metadata timestamp column has been left as "timestamp without time zone", and the MySQL custom metadata column has been changed from timestamp to datetime to keep the same behavior.
MIRTH-2892: Fixed destination queue issue where the same connector message is used repeatedly in the queue thread even after it's been deleted manually.
Fixed ChannelStatusServlet so that if isUserAuthorized() returns false, it will not execute the operation.
Issue: MIRTH-2894
