Overview

Resolves legacy product/support URL patterns to current canonical paths
via DB lookups. Used by Seo::InternalLinkValidator#suggest_correction to
provide actionable suggestions when Sunny writes a deprecated URL format.

All static redirect rules (category renames, path moves) are handled by
Cloudflare bulk redirects and the site_maps table — NOT hardcoded here.
