feat: add xeapi support and refactor eapi_decrypt to api_decrypt

- Added xeapi option to the API selection dropdown in api.html.
- Removed eapi_decrypt.html and created a new api_decrypt.html for unified API decryption.
- Implemented multi-crypto support in api_decrypt.html with corresponding UI changes.
- Created decrypt.js module to handle decryption logic for different crypto types including xeapi.
- Updated request.js to remove unnecessary debug logs and improve code clarity.
- Updated index.html to link to the new api_decrypt.html instead of the removed eapi_decrypt.html.
