autonomic-bot 47f7cb47c2 fix(2): F2-3 systemic — harness.browser.goto_with_retry; applied to all install overlays
Phase 2 lesson from F2-3 (n8n install Playwright flake on net::ERR_NETWORK_CHANGED): every
install overlay that does page.goto needs the same try/except PlaywrightError + status retry.
Centralize in runner/harness/browser.py::goto_with_retry; apply to ALL install overlays.

- runner/harness/browser.py: shared helper. Polls page.goto until status in accept_statuses;
  catches PlaywrightError (net::ERR_*) as a retryable signal, not a failure. Raises AssertionError
  with last_status + last_err diagnostic only on deadline expiry.
- tests/custom-html/test_install.py: now uses goto_with_retry (200 only, wait_until=load).
- tests/custom-html/playwright/test_browser_smoke.py: same.
- tests/n8n/test_install.py: replaced inline retry loop with goto_with_retry (200, 304).
- tests/keycloak/test_install.py: goto_with_retry for admin console (200, 302, 303; 45s goto).
- tests/cryptpad/test_install.py: goto_with_retry (200, 304; 60s goto, wait_until=load).
- tests/lasuite-docs/test_install.py: goto_with_retry (200, 301, 302; 60s goto).

Cold-verifiable: ssh cc-ci 'RECIPE=custom-html cc-ci-run runner/run_recipe_ci.py'
  all 5 stages PASS (including the install overlay that flaked in the deps_smoke run),
  deploy-count=1, head_ref=8a026066==chaos-version=8a026066 (HC1 non-vacuous).

"""custom-html — INSTALL overlay (Phase 1d layering proof, DG4).
Demonstrates OVERRIDE + EXTEND-by-composition: this file's presence makes the harness run it INSTEAD
of the generic install tier (override), and it reuses the generic assertion (`generic.assert_serving`)
then ADDS a recipe-specific Playwright content check (extend). Assertion-only — the orchestrator has
already deployed the shared app once (no deploy here, so deploy-count stays 1)."""
