ci: create ci workflow for multichain flow

[cortisiko]

Description

This PR addresses the new flows introduced with the updated network chain permissions functionality. The goal is to ensure comprehensive automated test coverage for these changes, reducing the risk of bugs found later in the development process.

Key things to note here:
breakdown of the CI workflows:

• Smoke Pipeline: This pipeline runs all E2E tests with an enabled multichain flag. This ensures that engineers actively validate the new MC flows as part of their workflow. By default, the smoke pipeline runs on pull requests, allowing us to catch any issues with the MC flow before changes are merged into the main branch. We plan to make the smoke E2E pipeline a required step before merging PRs soon.

• Regression Pipeline: This pipeline runs E2E tests with the multichain flag disabled. It ensures that existing functionality remains stable without the MC changes. The regression pipeline is scheduled to run every four hours against the main branch, providing frequent and consistent validation of the baseline functionality.
