improvement(seo): extract shared withFilteredNoindex helper (#5392)

The `{ ...base, ...(isFiltered && { robots: { index: false, follow: true } }) }`
faceted-navigation noindex pattern was duplicated verbatim across five
catalog pages (integrations, models, blog, careers, pricing). Extracted to
lib/landing/seo.ts alongside buildLandingMetadata, giving the pattern a
name and a single point of change. Pure refactor — verified byte-identical
rendered output (robots meta + canonical) on baseline and filtered variants
of all five pages before and after.
