feat: add calendar scheduling feature for agent teams

- Implemented FindCalendarSchedules method in agentTeamScheduleService to retrieve schedules within a specified time range.
- Added new API endpoint fetchAgentTeamScheduleCalendar to fetch schedules for the calendar view.
- Created ScheduleCalendar component to display agent team schedules in a calendar format with drag-and-drop functionality for moving and resizing schedules.
- Updated EditDialog component to support deleting schedules and handling default values for new entries.
- Enhanced DashboardAgentTeamSchedulesPage to toggle between calendar and list views, and to load calendar data based on selected week.
- Added tests for FindCalendarSchedules to ensure correct schedule retrieval and validation of time ranges.
