fix: keep bold labels in nested profile blocks

The nested list structure stays, so each label renders bold instead of showing its asterisks. The platform details block becomes a list as well: its labels were paragraphs followed by items with no blank line between them. validate_site now reports any asterisks that reach a rendered page outside code, which runs in the deploy and in pipeline step 8b.
