LocalClipboardManager/ClipboardManager are deprecated in Compose in favor
of LocalClipboard's suspend Clipboard API. Migrates the one call site,
ReportReviewScreen's "Copy report" action: LocalClipboardManager.current
becomes LocalClipboard.current, and the synchronous
clipboard.setText(AnnotatedString(...)) becomes a suspend
clipboard.setClipEntry(ClipEntry(ClipData.newPlainText(...))) run inside
the existing rememberCoroutineScope(). The clipboard interaction is
pulled into a small internal suspend function, copyReportPayloadToClipboard,
so it's unit-testable against a mocked Clipboard without an emulator.
Closes#237.
