Switch to static output and add Azure SWA deployment

- Set output: 'static' in astro.config.mjs; remove Vercel/Netlify adapters
- Remove API routes (contact, newsletter) incompatible with static mode
- Add Azure SWA deploy workflow using @azure/static-web-apps-cli via npx
- Add public/staticwebapp.config.json for SWA routing and 404 fallback
