sendTicketNotification() and sendStatusChangeNotification() always sent
the ticket title to the shared MATRIX_NOTIFY_USERS list regardless of
visibility, unlike sendCommentNotification()/notifyWatchers() which
already redact the comment/activity preview for non-public tickets.
Creating or changing the status of a confidential ticket broadcast its
title to a shared Matrix room, defeating the point of the Confidential
visibility level.
Added a shared redactedTitle() helper and threaded visibility through
both functions (sendTicketNotification reads it from the existing
$ticketData['visibility'] key; sendStatusChangeNotification takes a new
optional parameter, wired up in both callers from the already-fetched
ticket row). Verified end-to-end with a local HTTP server capturing the
actual webhook payloads: public tickets pass the title through
unchanged, confidential/internal tickets get the redacted placeholder.
