Subject: Add inline image insertion for page bodies, plus a headline-conflict
 badge

Custom TinyMCE toolbar button opens a picker scoped to a page's own
attached images. Selecting one and a placement (full width, left,
right) inserts <a class="glightbox" data-gallery="page-N">
wrapping an <img>, sharing the existing headline-image lightbox
gallery. No native TinyMCE image dialog or resize handles --
placement is fixed to the three options via CSS classes only.

extended_valid_elements defines a and img explicitly and
symmetrically; valid_classes allows the placement classes and
glightbox specifically. content_style renders placement inside the
editing iframe, since ccc.css doesn't load there.

A pre-save pass removes any a.glightbox left without an img,
covering in-editor deletion regardless of how it happened.

Alt text comes from the asset's name, escaped.

A badge marks whichever attached image sits at position 0, since
_headline_image.html.erb always renders that position as the
page's automatic headline. Shown in the sidebar Images list and in
the picker grid.
