ExportViewingKeyScreen class

Settings → Security → Export viewing key (#397 §3.7 D5 / ADR-0538): the ONE sanctioned UFVK egress into the UI. Clones the backup screen's gating — the host RE-AUTH gate (WalletRevealAuthorizer), screenshot/recents protection, the shoulder-surf reveal latch with auto-hide on background, and the autoDispose read — because the CONSEQUENCE being confirmed (total history surveillance) deserves the same deliberate bar as the seed, even though a UFVK cannot spend.

DIVERGENCE from the backup screen: a UFVK is PUBLIC once shared, so the artifact IS copyable + QR-able (a seed never is). The D9 warning copy states, in plain words, exactly what sharing this key does — everything received AND sent, past and future, becomes visible; it cannot spend or reach the seed; share only with someone trusted; the only un-share is moving funds to a new wallet.

SOURCE (G1, #361 companion): the provisioner when the package owns provisioning, ELSE the WalletSession port — so a session-only host reaches a WORKING export here instead of the pre-G1 dead end. Only a mount with NEITHER seam renders the honest managed-by-host terminal state. The D9 envelope below (re-auth gate, un-share warning, screen security, autoDispose) is identical on both paths — but the package's DEFAULT reveal authorizer is pass-through, so a host mounting this route owes an override of walletRevealAuthorizerProvider for the gate to mean anything.
