Add presubmission filter functionality to MeetingSchedule component

This commit introduces a new filter for presubmission teams in the MeetingSchedule component. It adds an AddRemoveFilter for managing teams whose events require presubmission, allowing users to add or remove these teams from the scheduled list. The corresponding methods for adding and removing presubmission teams are implemented, enhancing the component's functionality and improving user experience in managing event teams.
