Customizable delay for last-minute booking messages

Problem: Currently, Hospitable intentionally schedules check-in messages 30 minutes after acceptance for last-minute bookings (reservations made after the intended check-in time). This delay can be too long for guests arriving immediately.

Current Workaround: Manually clicking the "Send now" button to bypass the schedule.

Impact: Increased manual effort for the host and a potential delay in critical information reaching the guest during a last-minute booking.

Proposed Solution: Provide a setting to customize or reduce this 30-minute delay, or allow hosts to opt-out of the delay entirely.

Unlock: Hosts will have more control over their guest communication timing, ensuring guests receive check-in details immediately regardless of when the booking was made.
