🧪 Implement Complete Test Cases for Every Component, Hook, Utility, API Flow & Desktop Workflow

[abhishek-nexgen-dev]

CommDesk currently lacks exhaustive automated testing coverage across the application architecture.

This issue introduces a complete enterprise-grade QA ecosystem where every:

• Component

• Hook

• Utility

• Service

• Store

• API flow

• Feature module

• Permission flow

• Tauri integration

• Auto-update workflow

• Desktop interaction

must have production-grade automated test coverage.

This issue upgrades the testing system from partial coverage to a fully scalable, maintainable, CI-enforced testing architecture.

Reference QA standards:

---

🎯 Main Objective

Create a production-grade testing infrastructure where:

✅ Every component has unit tests
✅ Every hook has tests
✅ Every utility function has tests
✅ Every feature flow has integration tests
✅ Every critical workflow has E2E tests
✅ Desktop-specific features are validated
✅ Cross-platform behavior is verified
✅ CI blocks broken PRs automatically
