fix(builder): un-hide and relabel static-page content editor, warn on publish/remove-language

- KNOWN-ISSUES item 11: the WYSIWYG page content editor was buried inside
  a collapsed Advanced <details>, labeled 'Raw HTML (advanced)'. Moved it
  to the top of the Content tab, unwrapped, relabeled 'Page Content' /
  'Содержимое страницы' / 'Эջի բովանդակություն' with a plain-language
  description. Advanced tab keeps genuinely technical fields (id, slug,
  route, custom template).
- Publish (save-bar) and Remove language (languages-section) had no
  confirmation despite being destructive/high-impact — added
  window.confirm guards using the existing builder.confirm* i18n pattern
  (matches resetDraft/resetSection/dirty-guard precedent), all 3 locales.
