Add Integration Tests for GroupingWorkflows and Ensure Idempotency in License Attachment

[sebsadface]

Description

This PR introduces integration tests for GroupingWorkflows and ensures idempotency when attaching license terms in GroupingWorkflows.

Key Changes

• Added the attachLicenseTerms helper function, which attaches license terms only if they haven't been applied already. GroupingWorkflows now uses this helper instead of calling LicensingModule directly.
• Removed the local implementation of StorageLayoutCheck and updated DeployHelper to import it directly from protocol core.
• Added BaseIntegration.t.sol and Users.t.sol to encapsulate setup logic for integration tests and mock user creation.
• Added tests to cover all functions of GroupingWorkflows, including multicall scenarios, running in a forked public testnet environment.
• Added a temporary file to store the latest core protocol deployment addresses.
• Modified StoryProtocolCoreAddressManager to optionally read from the temporary deployment address file when the isTest flag is true.
• Miscellaneous Fixes: Added EVM version, removed unnecessary imports, fixed state variable visibility, and applied minor style improvements.

Test Plan

All existing and new tests pass locally.
