Capture deterministic preview screenshots from MailglassAdmin.PreviewLive.

The workflow is maintainer-focused and intentionally bounded: Chromium captures provide preview-pipeline confidence only; they do not claim cross-client parity.

mix mailglass_admin.preview.capture --dry-run
mix mailglass_admin.preview.capture --theme dark --widths 375,768
