A session can be saved while it is still running

You can now add a work session that is still running. Leave the end time empty, and the session saves as in progress, with a live timer in place of the end time until someone stops it.

Before, an empty end time turned the field red and kept Save switched off. The only way to record work in progress was to wait for it to finish and enter both times afterwards.

This covers the last 24 hours, so an overnight shift counts: a session that began the evening before can still be saved as running after midnight, when its start time sits on the previous day. Older sessions are unchanged and still take both times, since a session that far back is finished, not running.
