Widget: Calendar month view doesn't show events more than 5 days in the past

[dasgarner]

The provider doesn't seem to return events in a sensible time frame for the type of calendar.
$iCalConfig['filterDaysAfter'] and $iCalConfig['filterDaysBefore'] don’t seem to be right.

For monthly calendar, for example, we would expect it to return the events for the current month.:

• Set Events from the start of the to month
• for an interval of of 1 month
• Should show the month event, but it gets days before and after wrong
  • Range start: 2024-01-01 00:00:00, range end: 2024-02-01 00:00:00, config: array ( 'replaceWindowsTimeZoneIds' => false, 'defaultSpan' => 1, 'filterDaysBefore' => 5, 'filterDaysAfter' => 33, )
