Log event creation to admin audit log, add back button, bump to 1.10.3

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.
