Enable dev mode for React app with proxy support; refine build, styles, and UI.

- Adjusted `package.json` scripts for Bun dev server and build flow.
- Added `dev.html` for standalone web development with hot-reload enabled.
- Introduced `WebDisableEmbedded` and `WebDevProxyURL` configurations to support proxying non-API paths.
- Refactored server logic to handle reverse proxy for development mode.
- Updated `App.jsx` structure, styles, and layout for responsiveness and dynamic padding.
- Improved login interface with logo support and cleaner design.
- Enhanced development flow documentation in `README.md`.
