Migrate to Stack A: PHP-fpm + nginx + supervisord, drop flat HTML + Python API

- Remove old flat HTML pages (index, about, blog, contact, reviews, services/*, locations/*)
- Remove Python/Flask API container (api/)
- Remove old root nginx.conf and components/
- Add infra/: full nginx.conf (http block at /etc/nginx/nginx.conf), php-fpm-pool.conf (TCP listen), supervisord.conf, entrypoint.sh (auto-generates ALTCHA_HMAC_KEY)
- Add src/: PHP router, page/service/location/blog templates, contact handler, altcha handler, promo endpoint, SQLite data files
- Rewrite Dockerfile: single container, tini PID 1, healthcheck, all env vars declared
- Update docker-compose.yml: port 8096, env_file, healthcheck
- Update .dockerignore: exclude .env.*, include robots.txt/sitemap.xml/404.html/500.html
- Update assets: tokens.css, promo-popup.css/js, altcha.min.js, refactored form.js/main.js

Verified: all 17 routes 200, protection audit PASS, Resend confirmed working
