Align documentation and Docker configuration with current implementation

- Fix README.md: Make Docker deployment recommended, remove duplicate installation section
- Fix Dockerfile: Copy correct source files (unraid_mcp/, uv.lock, README.md) instead of non-existent unraid_mcp_server.py
- Update docker-compose.yml: Enable build configuration and use .env instead of .env.local
- Add missing environment variables to .env.example and .env: UNRAID_AUTO_START_SUBSCRIPTIONS, UNRAID_MAX_RECONNECT_ATTEMPTS
- Fix CLAUDE.md: Correct environment hierarchy documentation (../env.local → ../.env.local)
- Remove unused unraid-schema.json file
