test(e2e): fix race condition and locator iteration in number filter test

Replace textContent()+toBe() with toHaveText() locator assertion so the
paging status check retries until the filter is applied. Fix row loop to
use expected.length and .nth(i) — rows.length on a Playwright Locator is
undefined, so the loop was silently never executing.
