Story Title
Create initial UI tests for basic navigation and interaction.
Description
We need to define and implement a minimal set of UI test cases using Playwright to improve our current test coverage.
While OS-level features (like auto-update or system integrations) cannot be tested through Playwright, we can still cover meaningful UI flows to ensure stability and regression safety.
OS features and auto-update remain out of scope.
