Pull Request type

Please add the labels corresponding to the type of changes your PR introduces:

• Feature: Enhanced error handling for estimate_fee calls, including specific transaction hash in error data for failed and reverted transactions

What is the current behavior?

When requesting a fee estimate, the call expects a list of transactions. However, if the call fails, it returns an error without context, making it difficult to identify which specific transaction caused the failure.

What is the new behavior?

• Error enum has been updated to distinguish between transactions that failed and those that were reverted.
• If an error occurs, the hash of the transaction is now returned in the data field of the ContractError, distinguishing whether it is reverted or rejected.
• This change makes it clear which transaction caused the error, allowing you to preview executable transactions by simulating the transaction list.

Does this introduce a breaking change?

No

Isn't this a duplicate with #1555? @hhamud ?

its more specific to their case of just piping back a list of reverted and failed transactions when calling a specific function. My PR is more general change of piping whatever error back to the user.
