fix(docker): correct build errors, dead code and missing config

[luiscruzcwb]

Summary

• Dockerfile: remove COPY of postcss.config.js and tailwind.config.js — Tailwind v4 uses the @tailwindcss/vite plugin, these files don't exist and break docker build
• Dead code: remove .docker/nginx/ directory (9 files) — never copied into the image, referenced dockerize which is not installed
• add-env-vars.sh: fix env prefix REACT_APP_ → VITE_ (this is a Vite project); remove _writeNginxEnvVars which depended on the missing dockerize binary
• docker-compose.yml: drop deprecated version: field, remove NODE_ENV=production (irrelevant in the nginx:alpine final stage), add healthcheck using the existing /health endpoint
• docker_build.sh: fix registry atendai/ → evolutionfoundation/, add buildx multi-platform (linux/amd64,linux/arm64), guard missing VERSION argument with set -e
• .dockerignore: add to exclude node_modules/, .git/ and build artifacts from Docker build context — reduces build context size significantly

Test plan

• docker build . completes without errors
• docker compose up starts the container with healthy status
• docker_build.sh <version> pushes to evolutionfoundation/ registry for both platforms

Summary by Sourcery

Fix Docker build and compose configuration for the Vite-based frontend and clean up unused Docker-related assets.

Bug Fixes:

• Correct environment variable prefix in add-env-vars script to use VITE_ for injecting frontend env vars.
• Remove references to non-existent Tailwind/PostCSS config files from the Docker build to prevent build failures.
• Drop unused nginx env templating that depended on the missing dockerize binary.

Enhancements:

• Update docker_build script to use the evolutionfoundation registry, add multi-platform buildx support, and tag images with version and latest.
• Simplify docker-compose service configuration by removing deprecated and unnecessary settings and adding a container healthcheck.
• Add a .dockerignore file to significantly reduce Docker build context size by excluding dependencies, VCS data, and build artifacts.
• Remove obsolete nginx configuration directory that was never used in the current Docker image.

Reviewer's Guide

Updates Docker-related tooling and configuration to align with a Vite/Tailwind v4 frontend, fix broken builds, remove unused nginx/dead code, and improve image build/publish behavior and compose health checks.

File-Level Changes

Change	Details	Files
Align environment-variable injection script with Vite and remove unused nginx-related helpers.	Change frontend env var prefix filter from REACT_APP_ to VITE_ when generating ENV JSON for index.html. Remove _writeNginxEnvVars function that depended on the missing dockerize binary. Remove unused SSL helper function and its calls, leaving only the frontend env injection call.	.docker/add-env-vars.sh
Improve Docker image build script to support multi-arch builds and use the correct registry and tagging scheme.	Enable strict error handling with set -e and require VERSION argument via parameter expansion. Switch image registry/name from atendai/evolution-manager-v2 to evolutionfoundation/evolution-manager-v2. Use docker buildx build with linux/amd64 and linux/arm64 platforms, tagging both versioned and latest images and pushing directly from the build.	docker_build.sh
Modernize docker-compose configuration and add container health checking.	Remove deprecated top-level version field from compose file. Drop NODE_ENV=production environment setting from the nginx-based container as it is unused. Add a healthcheck that polls the existing /health endpoint via wget with configured interval, timeout, and retries.	docker-compose.yml
Fix Dockerfile to match current Vite/Tailwind v4 setup and avoid copying non-existent configuration files.	Stop copying postcss.config.js and tailwind.config.js into the build context since Tailwind v4 uses @tailwindcss/vite and these files are absent.	Dockerfile
Reduce Docker build context size by ignoring unnecessary files.	Introduce a .dockerignore file that excludes node_modules/, .git/, and build artifacts from the Docker context.	.dockerignore
Remove unused nginx configuration assets that are no longer part of the image build.	Delete nginx default.conf, include.d configs (cache, nocache, letsencrypt, spa, ssl, ssl-redirect), and sites.d backend/frontend configs under .docker/nginx since they are never copied into the image and referenced a non-installed dockerize binary.	.docker/nginx/conf.d/default.conf .docker/nginx/include.d/allcache.conf .docker/nginx/include.d/letsencrypt.conf .docker/nginx/include.d/nocache.conf .docker/nginx/include.d/spa.conf .docker/nginx/include.d/ssl-redirect.conf .docker/nginx/include.d/ssl.conf .docker/nginx/sites.d/backend.conf .docker/nginx/sites.d/frontend.conf
