implement stuck funds recovery and emergency admin operations

[Divineifed1]

Description:
Safety mechanism to recover incorrectly sent tokens or handle edge cases where users lose funds due to platform bugs. Admin operations must be time-locked and transparent.

Key functions:

• emergency_withdraw(env, asset, to, amount) — timelocked admin
• recover_token(env, asset, to, amount) — for accidentally sent tokens
• set_admin(env, new_admin) — admin transfer with delay

Acceptance criteria:

• emergency_withdraw has 24-hour timelock (stored as pending_until)
• recover_token only works for tokens not owned by the contract's intended logic
• All emergency ops emit EmergencyAction event with reason hash
• Admin transfer requires 48-hour confirmation period
• Tests simulate timelock expiry and cancellation

I'd like to work on this issue. I have a clear implementation plan for the stuck funds recovery and emergency admin operations and will deliver a secure, well-tested solution. Please assign it to me.

Hi, I would like to work on this issue.

I am interested in taking on this issue. I have reviewed the requirements for implementing the time-locked emergency recovery mechanisms and am ready to implement the solution.
Here is my proposed approach for the implementation:

1. Timelock and Governance State: I will design a storage layout to securely track pending administrative actions, including emergency withdrawals and admin transfers. These will include explicit timestamp records to strictly enforce the 24-hour and 48-hour execution delays.
2. Recovery and Validation Logic: I will implement the recover_token function with precise internal accounting checks to guarantee it can only target assets accidentally sent to the contract address, leaving active operational funds untouched.
3. Event Emission and Transparency: Every initiated, executed, or cancelled emergency action will emit an EmergencyAction event containing a cryptographic hash of the operation's parameters and justification for complete on-chain transparency.
4. Timelock Simulation Testing: I will write a comprehensive test suite that manipulates the environment block timestamps to thoroughly simulate pending periods, successful executions upon expiration, and unauthorized execution rejections.
   Please assign this issue to me so I can begin working on the implementation.

I've gone through the issue and I'd love to resolve it within the day.

I would implement a secure recovery mechanism where incorrectly sent tokens or funds affected by platform bugs can only be recovered through a transparent, auditable process. All administrative actions, including fund recovery and contract upgrades, would be protected by a time-lock allowing users and auditors to review pending changes.
