Refactor StateScheduleHandout component to improve event occurrence filtering and display

This commit introduces a new StateScheduleHandout component for generating printable schedules for students, including a combined master list of events. It adds configuration options in appsettings.json for state abbreviations and special event filters, enhancing the scheduling functionality. The Program.cs file is updated to register the new StateScheduleHandoutOptions, and the Calendar and Teams components are modified to include links to the new handout feature. Additionally, utility methods for filtering event occurrences are implemented to support the new functionality, improving the overall user experience in managing state schedules.
