Subject: [PATCH] test(webkit): CacheStorage entry should survive page.reload()

Roll WebKit to r2328, which fixes CacheStorage disk persistence in
persistent contexts (httpRequestHeaderFields was missing from the
ResourceResponseData persistence encoder, so persisted responses failed
to decode and cache.match() returned null).

Add a persistent-context regression test (fixed by the roll) and an
ephemeral-context test. The ephemeral case is marked as expected to fail
on WebKit: an in-memory CacheStorage entry is not persisted across
reload, consistent with Safari.

Fixes https://github.com/microsoft/playwright/issues/41618
