Summary of Changes

Added explicit { timeout: 30000 } (30 seconds) to both cy.contains() assertions in the FromUrl.cy.js system test. The test downloads and installs a real extension from a live GitHub URL, which can take significantly longer than Cypress's default 4-second timeout. This makes the test flaky in CI environments with variable network latency.

Changes:

• Line 18: cy.contains('Installation of the component was successful.', { timeout: 30000 });
• Line 28: cy.contains('Uninstalling the component was successful', { timeout: 30000 });

Testing Instructions

1. Run the system test for the installer component:
   npx cypress run --spec tests/System/integration/administrator/components/com_installer/FromUrl.cy.js
2. Verify the test "can install and uninstall a component from URL tab" passes reliably.
3. Optionally simulate a slow network to confirm the increased timeout prevents false failures.

Actual result BEFORE applying this Pull Request

The test intermittently fails with:
AssertionError: Timed out retrying after 4000ms: Expected to find content: 'Installation of the component was successful.'
This happens because the default Cypress timeout (4s) is insufficient for downloading and installing an extension from an external URL.

Expected result AFTER applying this Pull Request

The test reliably waits up to 30 seconds for the installation and uninstallation to complete, eliminating flaky failures caused by network latency.
