Fix autocomplete value suggestion time range

[lukasolson]

Summary

Resolves #100584.

Prior to this PR, if you set the time range to "Today", the value suggestions (in both KQL and in the "Add a filter" dialog) would only include an hour, rather than the whole 24 hour time range. This was because we weren't properly rounding up the end date as the time range selector does.

Checklist

• Unit or functional tests were updated or added to match the most common scenarios

For maintainers

• This was checked for breaking API changes and was labeled appropriately

Release note

Fixes an issue with autocomplete value suggestions where the date range was sometimes incorrectly applied.
