Ticket: FOUR-18303

This PR introduces comprehensive Cypress tests for the Screen Templates Panel in screen-builder and enhances Screen Templates Panel visibility.

The tests check that:

• The Screen Templates Panel opens when the 'Templates' button is clicked
• The Screen Templates Panel closes when the 'X' button in the Panel is clicked
• The Screen Templates Panel is hidden when a control is clicked and an Inspector Panel should open

This PR also Ensures the 'Templates' button is always visible, even without package-versions or processmaker integration.

How to Test

1. Go to branch task/FOUR-18303 in screen-builder and processmaker.
2. Go to Designer → Screens. Create a Screen.
3. The 'Templates' button should display in screen-builder.
   • If you have package-versions installed, uninstall it and ensure that the 'Templates' button is still visible.
4. Run npx open cypress and npm run dev in your screen-builder terminal.
5. Run tests for ScreenTemplateSection.js in Cypress.
   • All tests should pass.
