feat(tests): enhance test coverage with integration and utility tests

- Updated QueueCard tests to use getAllByText for better resilience against multiple occurrences.
- Modified useCodexLens tests to check for error existence instead of specific message.
- Added mock for ResizeObserver in test setup to support components using it.
- Introduced integration tests for appStore and hooks interactions, covering locale and theme flows.
- Created layout-utils tests to validate pane manipulation functions.
- Added queryKeys tests to ensure correct key generation for workspace queries.
- Implemented utils tests for class name merging and memory metadata parsing.
