Bug 34939: Set hour:minute to 23:59 when inputing dates unless explicitly set

1. Find some places in the staff interface where data-flatpickr-enable-time is set to true. Examples: renew.tt or circulation.tt
2. Directly input a date in whatever date format you have specified in DateFormat but omit the hour/minute. Example: 12/12/2023
3. See that the hour/minute default to 00:00 if your TimeFormat is 24hr and 12:00 AM if your time format is 12hr
4. Apply patch, clear browser cache.
5. Try step again, setting a date like '12/12/2023'. The hour:minute should be added as 23:59.
6. With TimeFormat set to 24hr try entering a date with the hour:minute like '12/12/2023 11:22'. The hour:minute should be set to 11:22.
7. With TimeFormat set to 12hr try entering a date with the hour:minute like '12/12/2023 11:22 AM'. The hour:minute should be set to 11:22 AM.
8. Play with this in as many TimeFormat and DateFormat combonatinons as you can.
