📝 Summary

Fixes two e2e failures caused by recent changes in the server and viewer:

• Playwright print.spec.ts: the viewer modal now has a "Viewer settings" button (.viewer__settings). It was printed over the text at the bottom of page 1, which broke the snapshot comparison. The print styles now hide it, together with the modal header.
• Cypress attachments.spec.js › Create a new whiteboard file: the test looked for .preview .widget-file.whiteboard. The whiteboard class came from the whiteboard app's own viewer component, which the files reference widget no longer uses (it now renders <nc-viewer-file class="widget-file widget-file--interactive">, server aa6adad57ef). The test now checks only what Text is responsible for: the created attachment is a .whiteboard file and a preview widget is inserted for it.
