Agents with limited custom roles were receiving notifications (creation, assignment, mentions, new messages, SLA) for conversations they couldn't actually open. For example, an agent whose custom role only grants `conversation_unassigned_manage` was getting notified about conversations assigned to other agents. Notifications now go through the same `ConversationPolicy#show?` check that gates the conversation view itself, so an agent only gets notified for conversations they're permitted to see. Administrators and agents without custom roles are unaffected. --------- Co-authored-by: Sojan Jose <sojan@pepalo.com> Co-authored-by: Muhsin Keloth <muhsinkeramam@gmail.com>
