Breaking*: Request Routing for Safe App

[bh2smith]

Change Summary

To be included in release notes:

Major:

• Streamlines transaction decoding (for UI).
  • Adding support for TransactionSerializable & TypedData
  • previously was only UserOperation and Raw Messages
• decodeTxData is no longer a class method on NearSafe, but rather standalone:
  • Decoupling the Adapter from transaction decoding.
• NearSafe.requestRouter now offers fallback support for MPC/EOA Addresses:
  • This is primarily for WalletConnect.
  • Utilizes the "from" field in SignRequestData.params: EthTxParams to determine which account should sign.
• hash has been replaced with hashToSign in EncodedSignRequest.
  • Note that this is a userOpHash whenever the evmMessage is a UserOperation

Minor:

• Introduces clever type guard for TransactionSerializable
• new Utility Function NearSafe.encodeForSafe returning boolean.
• Replace EvmTransactionData with SafeEncodedSignRequest which naturally extends EncodedSignRequest from near-ca.

⚠️ This will introduce breaking changes!
