fix(helpdesk): drop stale require of removed app-flash partial

Commit 4890a28 folded templates/partials/app-flash.phtml into
app-toast-stack.phtml, which the base layout now mounts itself. 14
helpdesk views still required the deleted partial and crashed every
helpdesk page with a 500 (Failed opening required app-flash.phtml).
Remove the redundant requires; the unified toast stack continues to
render flash messages via the layout.
