feat: add Docker support and enhance environment configuration

- Introduce .dockerignore for Docker build optimization
- Add Dockerfile for containerization setup
- Update .env.example to clear Sentry variables and rename HOST to TELEGRAM_HOST
- Modify astro.config.mjs to conditionally exclude SSR dependencies in Docker builds
- Adjust postinstall script to safely handle missing .git directory
- Refactor telegram host retrieval for clarity and consistency
