Make the denser page-tree layout opt-in instead of hardcoded, so row density can be toggled per deployment via the COMPACT_PAGE_TREE runtime config flag. - doc-tree: extract ROW_HEIGHT_STANDARD (32) / ROW_HEIGHT_COMPACT (26); default the virtualizer row stride to STANDARD density. - client: isCompactPageTreeEnabled() in lib/config (reads COMPACT_PAGE_TREE, default true); used by space-tree and shared-tree to choose the row height. - server: EnvironmentService.isCompactPageTreeEnabled() and expose COMPACT_PAGE_TREE through the window runtime config (static.module).
