test(e2e): give the DASH collection round-trip its cold-load budget (#1632)

The "ClearKey reopens from recent and favorites collections" spec does
five cold `page.goto` loads of the dev-served app. On the CI runner each
one costs ~6 s, so the default 30 s test timeout expired on the last
route: every attempt in the affected runs ended as `timedOut`, and the
retry trace's final screencast frame shows `/workspace/global-favorites`
still on the startup screen at 29.7 s. The two reported "shapes" were
just where the clock ran out.

Size the test like the other multi-load specs (`test.setTimeout(90_000)`)
and assert the "All playlists" radio is checked before waiting for a row
only that scope can show, so a lost click fails on the toggle instead of
surfacing as a missing row.

Closes #1630
