IND-533 Support paymaster in gas estimations

[DrenIncentiv]

Description:

This PR implements IND-533, adding support for Paymaster integration in gas estimations within the UI-SDK. This ensures that estimated gas values more accurately reflect the actual cost when using a paymaster during UserOperation submission.

---

Changes Implemented:

• Updated the gas estimation flow to include a call to getPaymasterAndData if a Paymaster API instance is set.
• Adjusted the estimateUserOperationGas logic to take paymaster data into account during simulation.
• Ensured compatibility with existing setups where no paymaster is used (fallback to default behavior).

---

Testing:

• Verified gas estimation results with and without a paymaster present.
• Confirmed consistent integration with both native and token-based actions.
• Checked edge cases including empty paymaster responses and invalid data formats.
