Fix: update local _nav.html to use widget-driven nav

The blog app's local templates/_types/post/_nav.html was shadowing
the shared version due to ChoiceLoader priority. Updated local copy
to use container_nav_widgets while keeping the blog-specific admin
cog link. Removed debug logging from context processor.
