fix: use browser history in web mode for proper URL routing

The router was using memory history with initial entry "/" which caused
all routes to render the index component regardless of the browser URL.

Changes:
- Use browser history when not in Electron (for e2e tests and dev)
- Use memory history only in Electron environment
- Update test utilities to use persist version 2 to match app store

This fixes e2e tests that navigate directly to /board, /context, /spec
