Testing: End-to-end testnet integration test as a required CI gate

[joelpeace48-cell]

Context

Deploy scripts exist but there is no required CI gate that deploys to testnet and runs the full
register→credit→claim→redeem flow before release.

Scope

• CI job deploys fresh contracts to testnet (ephemeral), runs the E2E flow, asserts on-chain + DB state.
• Gate releases on this job; publish the run as an artifact.

Acceptance criteria

• No release proceeds unless the full on-chain E2E passes.

Verification

• A deliberately broken contract change fails the gate.
