fix: use correct `deploymentId` for `logs --prod`

[shiftinv]

Fixes #275.

Just hit this issue myself earlier, and figured I'd look into it. c: productionDeployment.id is the build(?) UUID, whereas .deploymentId is the 12-char ID the endpoint seemingly expects here. .deployment.id also exists, but since they're identical and both are used across the codebase, I assume either one is fine.
