chore: update DBIS contracts and integrate EIP-712 helper

Browse Source 
- Updated DBIS_ConversionRouter and DBIS_SettlementRouter to utilize IDBIS_EIP712Helper for EIP-712 hashing and signature recovery, improving stack depth management.
- Refactored minting logic in DBIS_GRU_MintController to streamline recipient processing.
- Enhanced BUILD_NOTES.md with updated build instructions and test coverage details.
- Added new functions in DBIS_SignerRegistry for duplicate signer checks and active signer validation.
- Introduced a new submodule, DBIS_EIP712Helper, to encapsulate EIP-712 related functionalities.
