RayXpress Direct Client Email Inbox Fix

This update fixes the Client Email Inbox 500 error when the inbound_emails table has not yet been imported.

The application now creates the inbound_emails table automatically when an authorized Master/Master Pro opens Client Email Inbox or when the dashboard notification endpoint polls.

No SQL import is required for this fix.

Direct emails to info@rayxpress.site are still collected through the production mailbox using IMAP/SSL when the PHP IMAP extension is enabled on the hosting account.
