feat(tests): separate validated tests section + waiting time column

- Validated tests no longer appear in the active tests table; they are
  shown in a dedicated collapsible "Validated Tests" section at the bottom
  (with its own sortable table and count badge).
- Added "Waiting" column to the main table showing elapsed time since
  last update for blue_evaluating tests, sortable so Blue Team can
  prioritise the oldest pending evaluations.
- Sorting by Waiting pushes blue_evaluating rows to the top and orders
  them oldest-first by default.
