E2E: remaining click-then-assert-on-route-capture races in notification specs #1795

What: tests/settings/notifications.spec.ts (Discord contract, ~line 1287) still reads preview and create payloads captured in page.route() handlers right after a click, which is the pattern that made four specs fail intermittently (fixed in #1790 for the save, test, delete and create paths). Other specs may share it.

Where: tests/settings/notifications.spec.ts and any spec asserting a route-captured variable immediately after a click.

Evidence: #1790 CI shard 3 failure analysis; the fixed specs now wait for the request first.

Severity: low

Suggestion: grep for route handlers assigning to outer variables followed by a bare assertion, and switch to page.waitForRequest/waitForResponse registered before the click.
