Digital signature module

What I delivered
- Built internal signing, external signing by email, and third-party eSign integrations including VNeID.
- Implemented signature revert and signer reassignment so an in-progress flow can roll back or change signers without restarting.
- Fixed bugs and refactored the module to keep multi-step signing workflows stable.
