fix(viewer): exclude nav logo from image viewer

Previously, the navigation title logo was incorrectly included in the image viewer's gallery. This change adds the `no-viewer` class to the logo image and updates the viewer filter to also exclude elements with the `nav-title-logo` class, ensuring the logo is not clickable or viewable in the image viewer modal.
