feat: add org landing page builder service

New service that generates static Astro landing pages for organizations
and deploys them to Cloudflare Pages at {slug}.mana.how.

Components:
- Landing Builder Service (NestJS, port 3030) with Astro template
- Admin UI in Manacore web dashboard at /organizations/[id]/landing
- TeamSection + ContactSection for shared-landing-ui
- Two org themes (classic dark, warm light)
- LandingPageConfig types in shared-types
- Docker + CI/CD integration for Mac Mini deployment
