fix(test): make home-coverage E2E race-resilient (unblocks master CI) (#1310)

## Summary
Master CI failing on `test-home-coverage-e2e.js` (from #1303). Two flaky
tests blocking all downstream PRs:
- search suggestions timeout (5s too tight)
- "Full health" click hits stale element handle

## Fix (test-only)
- Wait for `#homeSearch` visible before fill; raise suggestions wait 5s
→ 15s; accept `.suggest-loading` intermediate state
- Switch Full health click to locator (auto-retries on detach);
pre-click waitForFunction for non-zero bounding rect; force-click
fallback

No production code touched. PII preflight clean.
