feat(web): compact two-line HistoryEntry/NetworkEntry for the narrow column (#1616)

In the pinned monitoring column (embedded), the single-line entry headers wrap
badly. Add compact two-line variants gated on `embedded`:

- HistoryEntry: line 1 = time + client/server badge + elapsed + status; line 2 =
  method (and target, truncated) on the left with the controls on the right,
  where Replay becomes an icon (new ReplayButton element) next to Pin/Expand.
- NetworkEntry: line 1 = time + HTTP method + category + elapsed + status; line 2
  = the URL in a horizontal ScrollArea (new Text `nowrap` variant) with the
  expand toggle on the right.

The full-size (non-embedded) layouts are unchanged. `embedded` is threaded from
the History/Network panels into the entries.
