feat: integrate community PageType plugins (Phase D Step 6)

Replace old page-rendering emitters with PageTypeDispatcher emitter
and pageTypes array. Restructure quartz.layout.ts from three separate
exports to unified layout object with defaults and byPageType record.
Install content-page, folder-page, tag-page community plugins.
