feat(wiki): accent color + favicon (#0050)

Set the blue Docusaurus-style accent (#2b6cb0 light / #63b3ed dark) via injectCSS
on the app UI — the login page is excluded because Wiki.js renders it without
custom CSS, so a dark login card is not themeable and is left as-is. Mount the
ThreadNet favicon (favicon.ico + favicon-16/32 PNGs the browser tab uses) from the
platform-branding ConfigMap via subPath, overlaying only those files.
