keyhan f7974dd382 feat(landing,billing): public pricing, global discount, services bar & estimator
Backend
- Add platform-wide global discount (platform_settings: global_discount_percent),
  applied centrally in PricingCatalogService.computeTotalsFromDb so it reaches
  every real charge (previews, deploys, renewals, upgrades, invoices). Admin
  GET/PATCH /billing/settings/global-discount.
- Add unauthenticated PublicPricingController (catalog + calculate) for the
  public landing page, returning gross/net and the discount percentage.
- Bill application replicas by the user-selected footprint: app CPU/RAM/storage
  now all scale by replica count; the single-replica database stays unscaled.

Frontend
- Landing: Services bar (PaaS active, DBaaS, KaaS/LaaS "coming soon" with
  expandable runtime/database menus), transparent Pricing section (per-resource
  rate cards with cycle toggle + discount strikethrough), and a cost Estimator
  ("estimate your package").
- Optional services and the database are priced like runtimes: the estimator
  lets users pick their CPU/RAM/storage (and DB type) so the cost scales by need.
- Admin billing: global-discount editor.
- i18n: fa/en strings for services, pricing, estimator and global discount.
