Adds /whp/admin/ with: overview, server-settings, coraza-waf,
site-monitoring, user-management. Articles are product-neutral
(no VDS in titles or required framing) since super admin may be
offered as a separate service later. They're marked Draft via:
- 'Draft' sidebar badge on the group + each article
- A draft callout partial at the top of every page noting WIP
The super-admin-callout partial (renamed from vds-only-callout)
mentions VDS as today's most common way to get super admin without
locking the docs to that single product.
- Pulled the real inline SVG from anhonesthost.com (chevrons + wordmark
with 'Host' in teal #00d4aa)
- Override Starlight's SiteTitle component so the SVG is inlined rather
than loaded as <img>, letting currentColor follow the active theme
- Hub page header uses the same wordmark
- 'Knowledge Base' label sits to the right of the brand mark, hidden on
narrow viewports
