fix(www): inline brand Organization on pricing Product schema

Replaces dangling @id reference (resolved only on the homepage's
Organization node) with an inline Organization object so Google's
Product rich-results validator can resolve brand without cross-page
context. Also renames markdownAnswerToText to stripMarkdownLinks
to match what the helper actually does.
