Added donation message to Stripe and Email (#20828)

ref PLG-160

- Refactored donation handling logic to be processed within the
`checkout.session.completed` webhook event.
- Added support for capturing and storing donation messages from Stripe
sessions.
- Integrated donation messages into the email notifications sent to
staff.
- Added database integration.
- Removed redundant donation logic from the invoice.payment_succeeded
webhook, since custom fields isn't supported.
- Updated and added new tests
