feat(tiers): add display-name layer, push.frequency entitlement, and rename pricing cards

Reconciles tier docs with `PlanSeeder` reality (basic has price_threshold
and score_alerts; schema is stripe_price_id_monthly + stripe_price_id_annual)
and introduces the display-name layer from pricing-plan.md v2.

- PlanTier::label() + Plan::displayName() + PlanFeatures::displayName()
  expose user-facing names (Free/Daily/Smart/Pro); backend identifiers stay
  basic/plus/pro so every call site, Stripe mapping, and test keeps working.
- push.frequency key added to features JSON (none/daily/triggered), mirroring
  email.frequency so Daily's daily push is distinguishable from Smart/Pro's
  triggered push. Seeder, factory, free-tier stubs, and Filament form updated.
- Homepage pricing cards renamed: Basic→Daily, Plus→Smart; badge
  "Most Popular"→"Most pick this"; CTAs refreshed.
- docs/tiers.md change log records the full diff.

Fleet tier, 14-day trial copy, and Smart dark-card treatment deferred.
