If the admin signing key is compromised there was no recovery path without redeploying. This adds a dedicated rotation function so the backend can switch to a new key without touching the contract binary. - Add update_admin_pubkey(new_pubkey: BytesN<32>) — admin-only - Overwrites AdminPubKey in instance storage with the new key - Emits (admin, pubkey) event on successful rotation - Old signatures are immediately invalidated after rotation - Adds 4 tests: successful rotation + new key works, old key rejected after rotation (Error(Crypto, InvalidInput)), non-admin blocked (Error(Auth, InvalidAction)), not-initialized path, event assertion Closes zintarh#25
