- Skip onboarding in tests by setting UserDefaults before launch
- Update all addSource.* identifiers to addRemoteServer.* for new flow
- Switch from identifier-based to text-based element lookups (iOS 26 AXe limitation)
- Add Yattee Server credential support in instance setup
- Update baseline screenshots for Home tab and settings
