Multisig Emergency "Pause" & Recovery

[hman38705]

Descriptions:

Issue #8:

Developer Goal: Enhance the circuit_breaker.rs to support multi-signature approval for high-risk actions.

Technical Requirements:

1. Hierarchical Admin: Introduce a GuardianAccount (a Multisig address) in admin.rs.
2. Pause Function: e.current_contract_address().require_auth() if the caller is the Guardian.
3. Partial Freeze: Standardize require_closed() such that place_bet is blocked, but withdraw_refund remains open.

Verification Checklist:

• Mock Guardian account successfully triggers pause().
• When paused, place_bet returns ErrorCode::ContractPaused.
• When paused, claim_winnings or withdraw_refund still functions (Partial Freeze check).
• Only the Guardian Set (multisig) can call unpause().
• git checkout -b features/issue-Multisig Emergency "Pause" & Recovery
• Pr Request create your pr against develop branch
