fix(markup): match live twig templates for anchor wrap and content wrap

Three corrections after diffing the rebuild against the actual theme
twig templates (modular/news.html.twig, employees.html.twig,
about.html.twig):

1. section_title macro learns a `with_anchor` flag for the case where
   live always wraps the h2 in `<div class="anchor" id="">` even with
   an empty anchor id. Default behavior unchanged.

2. team_carousel macro drops its `.anchor` wrapper around the title.
   employees.html.twig renders the h2 directly — including the wrapper
   was producing an extra layout element on /team that live doesn't
   have.

3. index.html's news section now calls section_title with
   with_anchor=true and wraps the loaded news content in an outer <p>,
   reproducing the grav markdown pipeline's behavior (the outer <p>
   auto-closes on the first inner <p>, leaving one leading empty <p>
   that contributes the expected 10px margin).
