Marketing site (bargevasat.ir) + admin-editable store links + subdomain split

- New standalone Next.js marketing site under site/ (static export, SEO):
  landing, download/install guide (Bazaar/Myket/iOS-PWA/web), FAQ (JSON-LD),
  privacy, terms, support, /admin link editor. fa RTL, sitemap/robots/manifest.
- Backend: SiteLinksService (JSON-file persisted) + GET /api/site/links (public)
  + POST /api/admin/site/links (X-Admin-Token). ADMIN_TOKEN + Site__DataDir via env.
- compose: hokm-site service (:1520) + hokm_data volume for links JSON.
- CI deploy job builds + deploys the site container.
- deploy/SUBDOMAIN_SPLIT.md: nginx blocks, cert reissue, DNS, ENV split.
- Exclude site/ from root tsc + web docker context.
