fix(platform): stop generating main api resource pages

Main page files (e.g., resources/clusterroletemplate.mdx) are now
manually maintained following the vcluster pattern where partials
are auto-generated but main pages are always manual.

This allows adding custom documentation sections like platform-specific
RBAC verbs that won't be overwritten by loft-bot regeneration.

Partials (reference.mdx, create.mdx, etc.) continue to be regenerated
on each run.

Closes DOC-1196
