Pull request overview

This PR ensures that graphs have an end time for metrics tracking, addressing two scenarios: recording graph elapsed time and finish timestamp on failure in the Thor job manager, and handling missing WhenFinished/TimeElapsed values in the ESP timeline UI by falling back to the current time for still-running graphs.

Changes:

• In the Thor master graph manager, record graph elapsed time and finish timestamp when an exception occurs during graph execution.
• In the ESP timeline TypeScript code, relax the filter to no longer require WhenFinished or TimeElapsed, and fall back to the current time if neither is available.
