ROU-12717: Fix name of added event to marker pop-up

[rugoncalves]

This PR is for simply attaching to the correct event in the case of the Google Advanced Marker. For the new version of the markers, the click event is gmp-click and not click.

What was happening

• An warning was appearing in the console, when the click occurred.

What was done

• Changed the static string to use instead the enumerate with the correct provider event;
• Protected the code against errors;

Test Steps

1. Go to the test page;
2. Click on the marker;
3. See if the pop-up appears;
4. And if no warning appears in the console;

Checklist

• tested locally
• documented the code
• clean all warnings and errors of eslint
• requires changes in OutSystems (if so, provide a module with changes)
• requires new sample page in OutSystems (if so, provide a module with changes)

Pull request overview

This PR updates the Google Advanced Marker popup behavior to listen to the correct provider click event (gmp-click) via the existing constants enum, and attempts to harden popup content refresh to avoid runtime errors.

Changes:

• Switched marker popup click listener from a hard-coded 'click' string to Constants.Marker.ProviderEventNames.click (maps to gmp-click).
• Initialized _contentString with a default empty string.
• Updated refreshPopupContent() to use optional chaining / fallback when reading popup DOM content.
