fix: upgrade react-scripts to 5.0.1 for frontend Docker build compatibility

- react-scripts 4.0.3 -> 5.0.1 (Webpack 5, supports modern JS in node_modules)
- @monaco-editor/react 3.7.5 -> ^4.6.0 (resolves peer dep conflict with monaco-editor)
- Removed --legacy-peer-deps from Dockerfile (no longer needed, was causing ajv resolution issues)
- Added @babel/plugin-proposal-private-property-in-object as explicit devDependency
- Removed overrides section (not needed with react-scripts 5)
