Ticket: FOUR-18315

This PR introduces comprehensive Cypress tests for the Screen Templates Panel in screen-builder and adds template-fetching functionality to screen-builder.

The tests check that:

• My Templates are displayed when the 'My Templates' button is clicked in the Screen Templates Panel
• Shared Templares are displayed when the 'Shared Templates' button is clicked in the Screen Templates Panel

This PR also refactors the handling of templates data, and the show/close functionality for the Screen Templates Panel.

How to Test

1. Go to branch task/FOUR-18315 in screen-builder and processmaker.
2. Run npx open cypress and npm run dev in your screen-builder terminal.
3. Run tests for ScreenTemplateSection.spec.js in Cypress.
   • All tests should pass.
