style(web): one layout for second sidebars, right rails and filter rails - #2009

🟢 Confidence 10/10 · safe to merge. The head only adds a scene test that pins the filtersLabel trigger and sheet names, closing F1; no other file changed since the earlier review.
_{no findings · tests covered · risk low}

This head adds one scene test asserting a filtersLabel rail names both its top-bar trigger and its sheet, and that the old "Filters" button is gone. It closes the open finding and is safe to merge.

• settingsView fixture renders a dashboardPage with filtersLabel: "Settings"
• New scene test checks "Open filters" is absent, clicks "Open settings", asserts the "Settings" dialog holds the rail

Fixed since the last review

• ✅ F1 · Rail label naming the sheet and trigger has no scene test
