🖌️ feat(ui): always show colorful console banner for NewAPI in every environment

Add a branded console log to `web/src/index.js` that prints:

“We ❤ NewAPI  Github: https://github.com/QuantumNous/new-api”

Changes include:
• Remove the `NODE_ENV` guard so the banner appears in both development and production.
• Increase font size to 24 px and keep “NewAPI” in bold green for stronger branding.

This is a purely visual/developer-experience enhancement—no runtime behavior is affected.
