fix(inbox): auto-archive inbox item when marking done from issue detail

When viewing an inbox notification's issue detail and clicking the "Mark
as done" toolbar button, the inbox item was not archived — only the issue
status changed. Add an onDone callback to IssueDetail so the inbox page
can archive the notification alongside the status update, matching the
behavior of the list-item Done button.

Closes MUL-1594
