SEO: pricing-rich service schema, AggregateRating, tighter meta

- Service pages now include AggregateOffer in JSON-LD (priceCurrency
  NZD, lowPrice/highPrice/offerCount derived from each service's
  pricing.plans). Unlocks price-rich SERP results.
- Homepage LocalBusiness schema now includes AggregateRating and
  per-testimonial Review entries (5 stars, n reviews). Eligible for
  star ratings in SERPs.
- Puppy Visits meta description rewritten — was 241 chars opening
  with "Puppy Visits Introducing Puppy Visits..." Now a tight 144
  chars with Auckland keyword.
- Removed the dead /about-us static-pages entry; the 301 redirect
  in [slug]/+page.server.ts already routes it to /about, so the
  duplicate metadata was unreachable. Pruned matching dead branches
  in [slug]/+page.svelte and RouteSkeleton.svelte for clarity.
