test(ui): stabilize onboarding/modal dismissal in e2e helpers

Refactor test helpers to reliably dismiss onboarding and migration modals during
UI flows. Replace ad-hoc Settings-only dismissal with a unified dismissOnboardingModals
routine that targets privacy, migration, and settings dialogs via testids,
interacts with visible controls (checkbox, continue/skip/save buttons) and waits
for dialogs to hide. Increase resilience by repeating checks, adding short
settle delays, and tightening timeouts.

Also add data-testid attributes to PrivacyModal, SettingsModal and
DexieMigrationModal to make the selectors deterministic and reduce flakiness in
export/upload tests.

No production behavior changes.
