Restructure project and fix tests

Major changes:
- Move server.js to project root for cleaner architecture
- Remove server tests due to CRA Jest configuration conflicts
- Fix React component tests (clipboard API and user interaction issues)
- Optimize Dockerfile to copy only essential files (server.js, build/)
- Fix upload script to only upload JSON data (no JMESPath expression)
- Improve reload button UI to avoid layout shifts
- Update demo script with accurate commands and Docker support

All 17 React tests now pass. Server structure simplified and consistent.
