Replace the plain textarea for the homepage_teaser setting with the shared
TipTap rich-text editor, and render the teaser as sanitized HTML in the
portal hero's default layout.
- SettingsAdmin: teaser field now uses RichTextEditor (lazy-loaded, code-split
like PostEditor); rich fields render in a <div> wrapper instead of <label>.
- HeroElement: text-block lines flagged `html` render sanitized HTML.
- heroLayout: the default-layout teaser line is now an HTML line.
- admin.controller: sanitize homepage_teaser against the body allowlist on save.
- theme.css: collapse the teaser's nested block margins in the hero.
