[Bug][Contract] multisig_governance does not extend instance storage TTL

Issue #5

Missing Storage Instance TTL Bumping in multisig_governance

• Title: [Bug][Contract] multisig_governance does not extend instance storage TTL
• Labels: bug, contracts, high
• Location: contracts/multisig_governance/src/lib.rs
• Description:
  Unlike LendingPool, LoanManager, and RemittanceNFT, GovernanceContract never invokes extend_ttl on instance storage.
• Impact:
  If no governance proposal occurs within the ledger lifetime threshold, contract instance storage (KEY_ADMIN, KEY_TARGET, KEY_PENDING) will expire and become archived on Stellar, locking protocol governance.
• Suggested Fix:
  Add a helper bump_instance_ttl(&env) and call it across all methods in GovernanceContract.
