[Bug][Scheduler] Events are not visually aligned to time separators in the Timeline view

[PekoPPT]

Describe the bug
If there is an event that ends at a specific time, it does not visually end at this specific time, but instead it looks like the event ends a few minutes earlier. For example, if an event ends in 2:30 AM, it is displayed like the end of the event is at 2:27 AM.

To Reproduce

1. Open this StackBlitz example
2. Scroll the Scheduler to the right until you see the 2:30 AM header
3. See that the two events are not aligned within the 2:30 AM boundaries

Expected behavior
When an event is set to end at a specific time, its visual representation should end at the line representing the specific time, and not before/after it.
