Subject: [PATCH] feat(server): add raw body parsing for multipart/form-data
 and application/octet-stream

- Implemented a new middleware to handle raw body parsing for specific content types, allowing for larger payloads up to 5mb.
- Enhanced form body serialization to support Buffer input, improving compatibility with various data formats during proxy interactions.
