feat: initialize project with Docker, PostgreSQL, Redis, and Vue.js frontend

- Added docker-compose.yml for PostgreSQL and Redis services with health checks.
- Created frontend directory with initial Vue.js setup including package.json, vite.config.ts, and TypeScript configuration.
- Implemented main application structure with App.vue and HomePage.vue components.
- Added message fetching and posting functionality in HomePage.vue.
- Included necessary styles and scripts for Ionic framework integration.
- Developed a dev-stack script to manage Docker containers and run backend/frontend servers.
