Fix remaining review threads on the report queue dashboard

- Read the raw report status from Qt::UserRole in DlgMyReports, so regular
  users can comment on their own open reports again.
- Exclude the server's depth-0 seed row from the related-alt count.
- Dim only IP matches shared by more than the pair, not every IP match.
- Activate alts rows on double-click or Enter instead of `activated`, which
  fires on a single click on single-click platforms.
- Fold the reported-user bolding pass into the fill loop.
