Add dedicated /pricing page and lock launch tiers to Free/Daily/Smart

Consolidate pricing onto a single source. Pro is deferred from launch
(left dormant: no Stripe price, no card), so the offered set is 3 tiers.

- Extract the pricing grid and footer into shared components
  (PricingGrid.vue, landing/SiteFooter.vue); add a /pricing route
  rendering Pricing.vue; remove the pricing section from Home
- Repoint every upgrade link to the /pricing route (LandingNav and
  SiteFooter via RouterLink, UpsellBanner CTA) — no more #pricing anchors
- Bump Smart (plus) SMS daily limit 1 -> 3 (PlanSeeder + PlanFactory),
  update PlanFeaturesTest assertion
- Rewrite /pricing card bullets to match real entitlements (drop
  unbuilt promises: multi-location tracking, 14-day trend, supermarket anchor)
- Fix stale "1/day" SMS references in notifications.md, tiers.md, docs/tiers.md
- Delete unused resources/views/components/pricing-card.blade.php
