AetherEdu#253) Add circuit-breaker-style pause mechanism allowing administrators to halt sensitive contract operations in emergencies: - Create contracts/src/utils/pause.rs with PauseUtils implementing is_paused, require_not_paused, pause, and unpause with admin-only access control and event emission - Add Paused variant to StorageKey in utils/storage.rs - Add PauseUtils import and pause checks to 17 mutating functions in lib.rs (issue_credential, create_course, verify_credential, issue_credential_with_expiration, renew_credential, revoke_credential_registry, batch_update_expiration_status, mint_dynamic_nft, evolve_nft, fuse_nfts, transfer_nft, register_attester, attest_credential, revoke_attestation, deactivate_attester, reactivate_attester, issue_credentials_batch) - Add pause, unpause, is_paused governance functions - Add comprehensive pause_test.rs with 10 tests covering admin/non-admin pause, mutating methods blocked, read methods working, pause persistence, credential/NFT/attestation operations Closes AetherEdu#253
