Jakub Zych 5beb1c5634 fix: sanitize journal HTML instead of blanking it on a regex match
The three-regex gate could be bypassed (an attribute without a space,
<svg/onload>, entity-encoded or tab-split javascript: URLs, MathML
xlink:href, base, meta refresh, forms) and it blanked a whole post or
category when ordinary text such as "Data: 12 maja 2024" matched.

- sanitizeJournalHtml runs sanitize-html with the Journal plugin's
  bluemonday policy: UGC elements plus footer, class, schema.org
  microdata, four validated inline styles, footnote roles, dir=auto,
  two chat transcript data attributes; http, https, mailto and
  relative URLs only
- gateJournalHtml and isSafeJournalHtml keep their signatures; html is
  always the sanitized value and is never blanked
- post body, category content and both page payloads are sanitized;
  the blocked notice, its style and string, and the blocked props and
  content_blocked field are removed
- toPostView moves to postView.ts so list pages and cards do not load
  the sanitizer
- tests cover every bypass from the review, the Data:/metadata: text
  and an imported author footer; the SSR smoke expects the unsafe
  sample's safe paragraphs
