Implements the new Node Families E2E testing strategy, shifting the primary Playwright suite from Storybook iframes to a dedicated mock-wired app shell (`main.mock.html`). This provides higher-fidelity testing against the actual wallet UI and router without a Tauri runtime or login.
Also introduces an optional WebdriverIO + `tauri-driver` suite for native WebKitGTK webview validation, configured as a non-blocking CI job for Linux. A critical fix for `NymCard`'s `data-testid` prop is included to enable robust UI selectors across all E2E tiers.
Updates CI workflows, adds new scripts for mock builds and native tests, and provides comprehensive documentation in `e2e/README.md` for the tiered testing approach.
