CMF Viewer: detail window improvements

[filipppavlov]

Change the look of the detail window. It now has a hierarchy tree view on top and detailed info on the bottom.

• Show contents of all loaded files
• Use single clicks to navigate instead of double-clicking, and use a consistent "hyperlink" style for clickable fields
• Show curve data (keys, values)
• Remove filtering in some of the tables
• Add an area column to the index buffer view
• Make the detail window collapsible and collapsed on startup
• Move the detail window code into a separate file

Pull request overview

Updates the CMF Viewer “Details” UI by replacing the previous mesh-details tabbed window with a new collapsible detail window that presents a file hierarchy tree (top) and the selected item’s detailed data (bottom), and refactors that UI into a separate component.

Changes:

• Replaces UIRenderer::MeshDetailsWindow with a standalone UIDetailWindow component and updates renderer integration.
• Adds the new hierarchy/detail rendering implementation (uiDetailWindow.{h,cpp}) including navigation links and additional data views (e.g., curve keys/values, index-buffer area column).
• Adjusts supporting state/data APIs (e.g., CmfContent::Index() becomes const, StateCollection::Clear() now fires callbacks).
