refactor(tests): use getByRole instead of getByText for interactive elements

- Refactor ~47 test cases across 7 test files to use getByRole
- Improve accessibility testing coverage following Testing Library best practices
- Make tests more robust against text changes (i18n, copy updates)
- Test elements as users (especially screen readers) interact with them
