Script to transfer the proxy ownership of all the contracts

[diyahir]

Add script to transfer proxy ownership across all protocol contracts

This PR introduces a new script that facilitates the transfer of proxy ownership for all protocol contracts to a new owner address. The script:

• Takes a new owner address as input
• Requires user confirmation before proceeding
• Transfers ownership for all core protocol contracts
• Handles asset-specific contracts (Oracle and Trove Manager) for each configured asset
• Exits with an error if any transfer fails

This script will be useful for administrative operations and protocol upgrades where proxy ownership needs to be transferred to a new address/multisig.
