Update README with project-specific documentation and Docker deployment instructions

[Copilot]

Replace generic Next.js boilerplate README with BubblyMaps-specific documentation including clone/build/deploy workflows.

Changes

• Project overview: Added BubblyMaps description with feature list (MapLibre GL, NextAuth, Prisma, MinIO integration)
• Prerequisites: Node.js 20.x, Docker, PostgreSQL requirements
• Manual setup: Complete workflow from git clone master branch through environment configuration, Prisma migrations, build, and deployment
• Docker deployment:
  • Image build from master branch
  • Container run with environment variables
  • Docker Compose orchestration with lifecycle commands (up/down/rebuild/logs)
• Development: Local dev server, linting, and database management commands
• Project structure: Directory layout and technology stack overview

Example: Docker Deployment

# Build from master
docker build -t bubblymaps/web:latest .

# Deploy with compose
docker-compose up -d

# View logs
docker-compose logs -f web

Environment configuration moved from implicit to explicit with .ENV.EXAMPLE reference and complete variable documentation.

Original prompt

please update the readme to reflect my project. include how to manually clone and build from mastrr branch, and deploy the docker container that is built.
