Fix: Call handle-order-paid directly from webhook instead of relying on DB trigger

The database trigger approach wasn't working because the trigger either doesn't
exist or the required database settings (app.base_url, app.service_role_key) aren't
configured.

This is a simpler, more reliable solution:
- pakasir-webhook updates order to 'paid' status
- pakasir-webhook then directly calls handle-order-paid edge function
- No dependency on database triggers or settings

This matches how other parts of the system work - direct function calls with
environment variables, not database triggers.
