createEvent never called logAdminAction, even though 1.10.0 already listed event_created as a filterable action on the audit-log page — only updateEvent/deleteEvent actually logged. Event creation is now logged the same way, at every return path including the legacy pre-migration retry branches. Also adds a "Back to dashboard" link to Admin -> Audit log, matching the existing back-link pattern on the Cashup page.
