#20681 webviews: base red: composer gallery plays wait out a cold Vite

web / react-apps-check is red on base: the first case of composer-search-files-key.test.ts and of composer-capture.test.ts times out after 30 s waiting for the gallery frame to say it is ready. It also fails locally on a clean base.

The frame is not broken. A probe of the same frame reached ready and its play passed after about 20 s. The wait is cold Vite compiling the gallery for the first page, which takes over 30 s on a busy runner. The other cases in those files pass on the same frame.

This raises that first readiness wait to 90 s in the five composer play tests that share it. The play assertions are unchanged.
