Subject: [PATCH] feat: add page_settings JSON property + ACE JSON mode

- Add property :page_settings (Hash, default {}) to Page model
- JSON.parse string input in setter (form submits as text)
- Add collapsible 'Page Settings (JSON)' section to page form
- Support data-mode='json' attribute for ACE editor
  (html_edit.js.coffee: check textarea data-mode attribute)
