Add priority E2E tests: personas, error states, import/export, empty search

- PersonaTests: hub renders cards, detail shows info
- ErrorStateTests_Extended: gallery loading state, dashboard error recovery
- PlaygroundImprovementsTests: import/export round-trip, fixed weak assertion
- GalleryImprovementsTests: search no-results empty state
