Fix SEO/UX audit gaps: canonical tags, org schema, nav, header claims

Add canonical URLs and a sitewide Organization JSON-LD (linked via @id
to page-specific LocalBusiness/Service/Article schemas), move FAQ and
Reviews into the top nav, attach the 24/7 support claim to a tooltip
on the header badge instead of leaving it unexplained, drop the
unverifiable incidents_resolved stat from the hero terminal animation,
and clean up the empty-reviews state instead of showing a thin
placeholder.
