Adjust the UI for contract call arguments

[neithanmo]

Currently, the ledger application has a limitation of processing up to 10 arguments while operating in normal mode. When this threshold is exceeded, the application returns an error message. To process more than 10 arguments, users must switch to expert mode.
We propose either increasing or removing this argument limit entirely to improve functionality in a future release of the app

Following our discussion, we have agreed on the following points:

• Display Argument Count:
  The app will show the number of arguments in a contract call transaction.

• Display Arguments Hash:
  The app will display the hash of the serialized contract call arguments. Serialization follows the documentation:

  A length-prefixed list of function arguments, encoded as follows:
  
      A 4-byte length prefix, indicating the number of arguments
      Zero or more binary strings encoding the arguments as Clarity values. Clarity values are serialized as described in the section [Clarity Value Representation](https://github.com/stacksgov/sips/blob/main/sips/sip-005/sip-005-blocks-and-transactions.md#clarity-value-representation).
  

As a result, there is no need to modify transaction serialization or encoding within the ecosystem. Wallets should:

• Show the Number of Arguments:
  Display the count of contract call arguments.

• Show Arguments Hash:
  Display the hash of the arguments as described above.

• Optionally Display Arguments:
  Optionally show the arguments themselves.

Hashing Algorithm

• SHA256
