Fix firebase-app-distribution release ordering rejected by the Firebase API

[priitlatt]

Since around 2026-07-14, firebase-app-distribution get-latest-build-version and firebase-app-distribution releases list started failing with Request contains an invalid argument. for every app, with no changes on our side (reported in #500).

The Firebase App Distribution releases.list API now rejects the previously tolerated camelCase createTimeDesc. The documented grammar uses a space-separated desc suffix, i.e. createTime desc.

The catch is that OrderBy.value was doing double duty: it was both the value sent to the API and the token accepted by the public --order-by CLI argument. Simply changing it to createTime desc would fix the API call but break the CLI (--order-by createTimeDesc would stop working and the value would need quoting). This PR decouples the two.

Changes

• codemagic.google.resources.firebase.OrderBy now holds the documented API grammar (createTime desc / createTime) — this is the value sent to releases.list.
• Introduce a CLI-facing ReleasesOrderByArgument in the tool layer (argument_types.py) that keeps the single-token values (createTimeDesc / createTime) and maps to OrderBy via its order_by property. The --order-by argument and the list_releases action signatures now use this type, converting to OrderBy at the point where the action group calls into the service.

Effect

• firebase-app-distribution get-latest-build-version and firebase-app-distribution releases list work again against the updated API.
• The --order-by CLI interface is unchanged and fully backwards compatible: same createTimeDesc / createTime choices and createTimeDesc default, and the generated docs are unchanged.
