Fix Xbox proxy: Add proper header forwarding and streaming support

- Add query parameter forwarding (?api_key=... etc.)
- Add X-Forwarded-* headers for client IP tracking
- Exclude problematic headers (content-length, transfer-encoding, etc.)
- Add streaming support for large files (8KB chunks)
- Add root route handler
- Properly forward all HTTP methods
