test(mcms): replace legacy changeset usage

[graham-chainlink]

In the new changesets under mcms, we should be using the new changesets instead of the legacy changesets

[Copilot]

Pull request overview

This PR updates MCMS integration/unit tests to stop relying on legacy/mcms/changesets and instead use the newer mcms/changesets/* implementations, aligning test coverage with the migrated changeset APIs and datastore-based address resolution.

Changes:

• Replace legacy DeployMCMSWithTimelockV2 usage in Solana/EVM tests with mcms/changesets/deploy.
• Replace legacy transfer-to-timelock flows with mcms/changesets/transfer-to-timelock and refkey-based contract selection.
• Update Solana test runtimes to seed a datastore (program IDs) via solanatest.NewDataStoreWithMCMSPrograms rather than using an AddressBook.
