fabi b1e2e66305 test(e2e): address self-review follow-ups (dedup, XSS render guard, SSE hardening)
Follow-ups from the code review of the test-quality batches:

- Consolidate duplicated helpers into e2e/helpers/: seed.ts (seedUpload,
  seedComment, listComments, findFeedRow) and sse.ts (mintSseTicket, openStream,
  trackStreamOpens). Refactor authorization-deep, xss-injection, like-comment,
  sse-ticket-abuse, ddos, sse-realtime, multi-tab, and SseListener to use them —
  the upload/comment/ticket-flow contracts now live in one place each instead of
  being re-inlined across 3–7 specs.
- xss-injection display-name loop: it navigated to /feed (which renders uploader
  names, not the viewer's) so "nothing fired" passed vacuously — the payload was
  never rendered. Now navigate to /account (the actual sink) and add a render
  guard asserting the payload reached the DOM as escaped text before checking
  __xssFired.
- sse-realtime reconnect: snapshot the stream-open count AFTER backgrounding, so
  the "new connection" assertion is attributable to the foreground event and can't
  be satisfied by a spurious native/error reconnect before the toggle.
- recover-page: correct the comment (auto-submit is the onPinInput handler, not an
  $effect).

44 affected specs verified green.
