[Contracts] Multisig governance proposal state lives in instance storage and can be archived, stranding in-flight transfers

Why this matters

multisig_governance/src/lib.rs stores the entire PendingTransfer (with a 7-day PROPOSAL_TTL_SECONDS timelock window plus a min 24h delay) under instance storage (KEY_PENDING) and never bumps instance TTL anywhere in the contract. Unlike the other contracts, there is no bump_instance_ttl helper, so a long-lived proposal awaiting its timelock can have its instance storage archived, making finalize_admin_transfer and approvals fail and the contract effectively unusable.

Acceptance criteria

• Add instance-storage TTL extension on proposal creation, approval, and reads consistent with the other contracts
• Choose TTL bump values that comfortably exceed the maximum proposal lifetime (delay + PROPOSAL_TTL_SECONDS)
• Add a test that advances ledgers across the timelock window and confirms the proposal is still finalizable
• Document the storage-class and TTL choice for governance state

Files to touch

• multisig_governance/src/lib.rs

Out of scope

• Migrating governance state to persistent storage layout changes
• Adding multiple concurrent proposals
