fix: wiki index no longer bumps right; harden Harmony Inter/Poppins fonts

#30 — namespace index / section listing pages had their heading, lead, and
page list pushed into a narrow centered column with a big left gutter. The
listing card reuses the .wiki-article-prose class, so the article-body reading
treatment leaked onto it: the wiki plugin caps prose children at
--wiki-prose-measure (54rem) and the theme margin-inline:autos them. Opt the
.wiki-namespace-index card out of that measure/centering so the listing runs
full-width and left-aligned. Verified with a before/after render of the real
section markup against the compiled CSS.

Inter 404 (sow-nodebb#13) — Harmony emits Inter/Poppins @font-face at our asset
path and points its sans/secondary font vars at them, but we ship Jost + Cinzel
and declare no @fontsource/inter|poppins dep, so those URLs 404 in production
(they only resolve in dev via npm hoisting). Pin the Harmony rules that read
those vars directly (.ff-sans, .ff-secondary, breadcrumb divider) to our fonts
so nothing can request Inter/Poppins, and drop the two dead staticDirs. The live
404 clears once the nodebb image is rebuilt from current theme main.

+/* Harmony base-theme font correction.
+   Harmony generates @font-face for Inter/Poppins at our asset path and points
+   $font-family-sans-serif -> "Inter" and $font-family-secondary -> "Poppins"
+   in its own overrides.scss. We ship Jost + Cinzel, not those families, and do
+   not declare @fontsource/inter|poppins as deps -- so any element that resolves
+   to Inter/Poppins 404s in production on /assets/plugins/nodebb-theme-westgate/
+   inter/... (it only happens to resolve in dev via npm hoisting). Our BS-variable
+   override already keeps the current cascade on Jost, but that hinges on subtle
+   import order; pin the handful of Harmony rules that read those SCSS variables
+   directly (.ff-sans, .ff-secondary, the breadcrumb divider) to our own fonts so
+   nothing can request Inter/Poppins even if a Harmony bump flips the order. The
+   now-pointless inter/poppins staticDirs are removed from plugin.json alongside. */
