P3: These two .disabled traits drop the only test coverage for the header's responsive action placement (actions collapse to the overflow menu at 220pt; buttons stay inline at 420pt). The disable itself is justified by CI, but the reason string's re-enable path was not validated: CloudTreeHeaderActionsTests hosts row controls inside CloudSidebarOrderingFixture, while CloudTeamPickerHeader is a toolbar header with no such fixture-hosted site, so "hosted the way CloudTreeHeaderActionsTests hosts it" may not be achievable. The re-host follow-up also lives only in this PR's discussion. Create a tracking issue that owns re-hosting and re-enabling, and reference it in the reason strings instead of asserting an unverified re-enable path.

Keep both header regression tests active.

While disabled, changes to the narrow and wide CloudTeamPickerHeader layouts and accessibility identifiers are not checked. CloudTreeHeaderActionsTests hosts CloudTreeCellView section headers, not CloudTeamPickerHeader, so its existing fixture does not exercise this path. Mount the actual panel header through an app-host fixture that publishes its SwiftUI accessibility tree, then remove .disabled.

Review comment at @cmuxTests/CloudMachinesHeaderCountTests.swift at line 43:
Update both regression tests in CloudMachinesHeaderCountTests to mount the
actual CloudTeamPickerHeader in an app-host fixture that publishes its SwiftUI
accessibility tree, then remove the .disabled markers. Do not reuse
CloudTreeHeaderActionsTests’ CloudTreeCellView fixture, since it does not
exercise CloudTeamPickerHeader.
