Dependencies: Issue #4

Objective:
Migrate selected subset test cases from a3p proposals to the z:acceptance test phase and execute them to validate expected behavior.

### Tasks
- [x] Select Test Cases for Migration
- [x] Incorporate selected tests to the `z:acceptance` test phase
- [x] Execute and confirm the expected behavior

Select Test Cases for Migration

Some identified test cases are focused on the actions that can be executed on vaults, which are strong candidates for migration to a more unified structure.

The selected tests are:

• Vault Operations Validates various vault operations including opening, adjusting, and closing vaults, and verify the results. Test File: mainnet1B-rc3/packages/deployment/upgrade-test/upgrade-test-scripts/agoric-upgrade-10/actions.sh

The goal of this migration is to consolidate these tests into a single, dedicated test file for vaults behavior. This structure will serve as a foundation for future vaults-related test cases, allowing for easier maintenance and scalability.

Design decision

Currently, there is already an test-vaults.mts file that test operations related to changes on auctions parameters. I propose rename this test to auction.test and extend its coverage to all auction-related tests.
