test: fix flaky versions tests timing out on link clicks before hydration (#15790)

### What

Fix flaky versions e2e tests that timeout when clicking table row and
version links.

### Why

Since Next.js 16, clicking links before page hydration completes doesn't
trigger navigation sometimes. The test finds the link and clicks it, but
nothing happens, causing timeouts waiting for the page to load.

### How

Extract href attributes and navigate directly with `page.goto()` instead
of clicking. Also reduced typing delay in autosave test to complete
within timeout under CPU throttling.
