/levels/{level-id}/timeseries endpoint truncates end time when duration not divisible by 1 day

Describe the bug
For the /levels/{level-id}/timeseries endpoint, a timeseries the end time/value pair isn't returned if the requested time frame isn't divisible by 1 day. This is problematic because some users don't request in day chunks (e.g. plotting on a website). There have been some workarounds on the front end code for this, but it would probably be better to fix in CDA (tangentially related issue with trying to finagle the front end to deal w/ it https://github.com/USACE-WaterManagement/groundwork-water/issues/225).

Expected behavior
For a begin and end, I would expect a return of times/values for the begin, end, and any inflection points in between. What is returned appears to be a daily value beginning at the begin time and if the end time doesn't match a day interval from the begin time, we end up missing the last time/value pair.

Problem: The response "end" field says "2026-04-16T03:32:39Z" but the requested end was 2026-04-16T15:32:39Z (12 hours later). The data stops
short of the requested time window.
