[eas-cli] add apple platform value to observe commands

[kadikraman]

Why

Part of ENG-26159.

The dashboard's Apple platform filter covers iOS, iPadOS, tvOS, and macOS together, but the CLI's --platform flag could only express a single platform. We want to match the filters on the dashboard so we could correctly pre-fill them in the prompts.

This also fixes a bug: --platform ipados, tvos, and macos were accepted but silently queried iOS data.

How

Update all commands so that --platform apple will query all apple platforms. Other behaviour is unchanged.

Test Plan

Unit tests and querying locally on staging.

Metrics summary

eas observe:metrics-summary --platform apple
eas observe:metrics-summary --platform macos

apple renders one combined "Apple" section; macos now correctly reports no data for an iOS-only app (it previously returned the iOS data).

Metrics

eas observe:metrics tti --platform apple --limit 3

Routes

eas observe:routes --platform apple

Events

eas observe:events --platform apple            # summary of event names + counts

Versions

eas observe:versions --platform apple
