fix: Resolve WebSocket parsing and WASM serialization errors

**Motivations :**
- Fix JSON parsing error in parseNewTx method
- Fix process.states iteration error in handleHandshakeMsg
- Add debugging for WASM serialization issues
- Improve error handling for malformed data structures

**Modifications :**
- Fixed parseNewTx to handle both string and object inputs
- Added Array.isArray check for process.states before iteration
- Added debug logging for members data in createProcess
- Enhanced error handling for WebSocket message processing

**Pages affectées :**
- src/services/service.ts - Fixed parsing and iteration errors
