…icon UI bugs (#37681)

* Fix homepage width, card-title weight, and deploy-k8s code block clutter

The homepage's hide_table_of_contents:true dropped the usual 75% width
cap DocItem/Layout applies via docItemCol, so prose read much wider
than every other doc page. Restore the cap unconditionally.

CardGrid's card titles ("For End Users", etc.) used Archivo Black at
900 weight, the same too-heavy/shouty treatment already fixed for
h1-h4 — switch to the sans face at 700 to match.

On the Kubernetes Operator deploy page, strip inline "# comment"
annotations out of the YAML/shell snippets (moving anything useful
into surrounding prose), and replace nested blockquotes used purely
for list indentation with plain nested lists, since the blockquotes
were triggering the site's yellow-bordered blockquote styling at
every nesting level for no reason.

* Fix oversized Restore icon on the Send messages doc page

restore_F099B.svg was the only icon under docs/site/static/img/ui
missing explicit width/height attributes (every sibling icon sets
width="24" height="24"). Without them, the browser falls back to its
default SVG replaced-element size instead of the 24x24 the inline
.theme-icon usage expects, rendering it many times larger than the
surrounding text.
