Support Tentative Calendar Invites for Pending Booking Approvals

As a TidyCal user, I want any new booking request to automatically create a ‘tentative’ event on my connected Google Calendar (and other linked calendars) when the request is submitted - before I manually approve or deny it - so that:

• I block off that time on my calendar to prevent double-booking
• I can see all pending meetings at a glance
• Once I approve, the event status updates to ‘confirmed’ and the guest receives the official invite
• If I deny, the tentative event is automatically removed

This feature would streamline scheduling by giving me visibility into pending requests without waiting for my manual approval, and it reduces the risk of accidentally booking over that slot.
