Give the wider team read-only access with the viewer role

Organizations had two roles, admin and user, and both could act on what they saw. Muting a flaky test, deleting a preview, writing to the cache: a user could do all of it. Opening your build and test insights to the wider engineering team meant handing every one of them the ability to quarantine a test.

Members can now be added as viewers. A viewer reads projects, builds, test runs, previews, bundles, and runner activity, and cannot change any of it. Where a control would mutate something, a viewer sees the current value instead: a muted test case still reads as muted, it just cannot be un-muted from that page.
