Subject: [PATCH] Achieve 100% branch coverage on Dashboard and Store modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Store Module Improvements:
- authSlice: 87.5% → 100% branch coverage
- lib/store overall: 91.66% → 100%
- Added test for login without username in response (fallback branch)

Dashboard Component Improvements:
- DashboardHeader: 87.5% → 100% branch coverage
- Dashboard components overall: 87.5% → 100%
- Added test for mobile loading indicator state

TerminalModal Improvements:
- Added tests for Enter key and Shift+Enter key handling
- Better test coverage for keyboard interactions

Total: 242 passing tests (up from 238)
Overall branch coverage: 73.51% → 74.3%

Key achievements:
- 100% branch coverage: authSlice, DashboardHeader, all Dashboard components
- 100% branch coverage: ContainerCard, LoginForm, ContainerHeader
- 100% coverage (all metrics): API client, all TerminalModal sub-components
