What does this PR do?

I have added two options for the user to delete past bookings.

They can delete individual bookings like this:

Or they can delete all the bookings in one go using the main button:

• Fixes #18787
• Fixes CAL-5114

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. If N/A, write N/A here and check the checkbox.
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

1. Login with pro@example.com
2. Go to bookings
3. Click on delete button
