Fix Docker build issues and SQL worker configuration

- Fix .dockerignore to allow dist directory for Docker builds
- Add uint8arrays dependency for crypto operations
- Configure Vite for proper SQL worker bundling with absurd-sql
- Update Dockerfile with build context documentation
- Fix Nginx configuration for non-root user permissions
- Remove conflicting backend proxy configuration
- Add SQL worker polyfills to vite.config.common.mts

Resolves Docker build failures and ensures proper SQL database functionality
in containerized environment.
