Tobias Koppers 76e24273c7 test: stabilize read-only page recreation (#97674) ...

### What?

Stabilizes the read-only source HMR page deletion and recreation test in
webpack development mode.

### Why?

The test reloads after restoring a deleted page because webpack does not
automatically refresh when the route reappears. In polling watch mode,
that reload could wait for the full page load or be aborted by a
concurrent Fast Refresh navigation. Either error escaped the retry
callback, allowing one transient navigation race to fail the test before
it could retry.

### How?

The webpack-only reload now waits only until the document is available
instead of waiting on potentially slow subresources. Transient reload
failures are handled inside the retry callback, while the existing
page-content assertion remains the success condition. This preserves the
test's intent and ensures a route that does not recover still fails.

### Verification

- Fresh `pnpm build` followed by a cold headless webpack run: 3 passed
- Three additional headless webpack runs: 3 passed each
- Headless Turbopack run: 2 passed, 1 expected skip
- Focused Prettier and ESLint checks
