feat: max-bot-test initial — full surface coverage

- Slim 4 PSR-15 webhook, PHP-DI 7, Symfony Console 8
- 13 update handlers, 30+ command scenarios, all 7 button types
- Composer pulls pkirillw/max-bot-api-php from GitHub vcs
- Multi-stage Dockerfile (php-fpm 8.4-alpine) + nginx
- docker-compose.yml targets server (npm_default external)
- docker-compose.override.yml for local dev (gitignored)
- .gitea/workflows/deploy.yml mirrors ghost-blog-bot pattern
