Token "lock out" / frozen funds

Description: A Liftoff Program member has requested a way for funds to be deposited into a Multi-sig account and then have all outbound transfers of tokens be locked until an expiry date and time.

Story ROI: This feature supports Web3 Treasury management via Alberto that was requested by a customer and is valuable to Lifted internally as well.

As a company, I want the tokens in a multi-sig account to be locked until an expiry date so that they can not be transacted.

• Should be achievable via many-rs.
• Should be able to set an expiry date and time for when the tokens are released from lock up.
• Should be able to input the amount token that will be locked up.
• Should be able to input the account address that where the tokens are being locked up in.
• Should be able to transact tokens after they are unlocked after the expiry.
• Should be deployed to dev.
• Should be able to be demoed.

Tasks:

No files, tests, or entry points are mentioned. Start by locating the many-rs integration and clarifying how multi-sig token locking, expiry, amounts, and account addresses should be represented; done means the feature works through unlock, is deployed to dev, and can be demonstrated.
