   so cancelling a rename stored an EMPTY session name and the tab fell back to its

Fifth and sixth merged PRs, and the layout work also fixed real multi-user ordering leaks along the way.

 - Fix the file preview's dead pop-out control: a real detach button now opens the previewed file in a browser tab (raw route for PDFs/images/media/text, converted-PDF preview for docx/pptx) and the copy button reports when a preview has no text to copy instead of silently doing nothing. Review-driven hardening for the new tab features: PUT /api/session-order drops unknown ids again instead of rejecting the whole write (a session deleted inside the browser's debounce window could silently lose the user's reorder), a failed mux restore no longer blocks explicit session/webview deletion for the process lifetime (the automated stale sweep stays fail-closed), and the vertical rail gains the axis-awareness the sidebar-only predicates missed: correct drag-reorder insertion, active-tab scroll-into-view, floating windows anchored beside rail tabs, connector redraws on rail scroll, server-seeded orientation applied on first load, a pre-paint stamp so vertical mode no longer flashes through the header strip, and a 12px session-name default matching the sidebar's historical size so untouched installs are not restyled.
