fix(wiki): replace remaining Wiki.js favicons; split branding ConfigMap

The browser tab still showed Wiki.js because only favicon.ico + 16/32 were
replaced — the larger icons the tab picks (android-chrome-192, apple-touch-180,
mstile-150) were still the defaults. Add ThreadNet versions and subPath-mount
them. Adding these pushed the single branding ConfigMap to ~1.04 MB (the 1 MiB
etcd limit), so split the 604 KB background into its own platform-branding-bg
ConfigMap mounted at /_assets/img/bg; authLoginBgUrl follows.
