When an agent shares a conversation link copied from a custom view (e.g.
/custom_view/{id}/conversations/{id}), the link previously broke for
recipients who didn't have access to that custom view. The conversation
now loads regardless — if the custom view isn't available to the
recipient, they're redirected to the direct conversation URL.
### How to reproduce
1. As Agent A, open a conversation from inside a personal custom view
and copy the URL from the address bar.
2. Share the URL with Agent B who does not have access to that custom
view.
3. Before this fix, the link failed to load the conversation. After this
fix, Agent B lands on the conversation via the direct URL.
### What changed
- Added a beforeEnter guard on the conversations_through_folders route.
It checks the user's available conversation custom views (fetching them
on demand for deep links), and if the foldersId in the URL isn't among
them, redirects to the inbox_conversation route with the same
conversation_id.
