[PeerX Backlog # 85] Add a Treasury deposit function

[ameeribro4-sudo]

Problem Statement
Penalty amounts (Issue #38) and unstaked-stake-forfeited balances end

read-only treasury_balance(env).

Acceptance Criteria

• Penalty path credits treasury.
• Governance can withdraw via treasury_withdraw after timelock.

Files Affected

• peerx-contracts/counter/src/{staking_bonus,lib,errors}.rs.

Dependencies Issue #38.

Hi! I'd like to work on this issue.

I've reviewed the requirements and understand the objective is to introduce a dedicated treasury flow so protocol penalties and forfeited staking balances are tracked in a single, auditable location. I'll implement the treasury functionality while keeping it aligned with the project's existing governance and authorization patterns.

My plan is to:

• Add treasury_deposit and treasury_balance to the contract with persistent storage for treasury funds.
• Route penalty amounts and unstaked forfeited balances into the treasury instead of leaving them unaccounted for.
• Implement a governance-controlled treasury_withdraw flow protected by the project's timelock and admin authorization mechanisms.
• Add any required error types and storage updates to support the new treasury lifecycle.
• Write comprehensive tests covering deposits, balance tracking, authorized withdrawals after the timelock, unauthorized access, and edge cases to ensure existing functionality continues to work correctly.

I'll keep the implementation modular so future protocol revenue sources can reuse the same treasury infrastructure without duplicating logic.
