/**
 * SuperSync Wrong Password Error E2E Tests
 *
 * Verifies that when a client has the wrong encryption password (e.g., after
 * another client changed it), the DecryptError properly surfaces a password
 * prompt dialog instead of being silently logged.
 *
 * This tests the fix for: operation-log-download.service.ts DecryptError handling
 * - DecryptError should propagate to sync-wrapper handler
 * - DialogHandleDecryptErrorComponent should open
 * - Sync status should show ERROR icon
 * - User can enter correct password and retry
 *
 * Run with: npm run e2e:supersync:file e2e/tests/sync/supersync-wrong-password-error.spec.ts
