Schedule non-appointment events in the calendar

Allow adding calendar events that are not client appointments and not time off, such as meetings and consultations, administrative tasks, reminders and follow-ups, and personal appointments or other scheduling blocks. These events would not need to be connected to a client or categorized as time off, and there should also be an option to create recurring events. As a practice owner, the workday includes more than client appointments, and being able to schedule different types of events would make Upheal's calendar more functional as an all-in-one scheduling tool.
