Integrate WASM, CipherPodLedger module and Enhance DA Layer with Integrity Checks (#6, #24)

- Added support for WASM integration to enable RUST-based contract deployment.  
- CipherPodLedger module, enabling FHE-based pod settlements in Junction.
- Implemented `LogBlobData` and `IntegrityCheck` functions to improve blob integrity in the DA layer.  
- Resolved bugs in WASM module test cases and added edge-case test coverage.  

Closes #6, #24
