chore(docker): add .dockerignore and update Dockerfile

Add .dockerignore to exclude node_modules, .git, coverage, .env.
Update Dockerfile to install nodejs/npm, copy package.json, run npm install, and build.
Update compose.prod.yml to set working_dir, restart no, and use array command.
Move drizzle-kit from devDependencies to dependencies.
