feat(page-tree): gate compact tree density behind COMPACT_PAGE_TREE flag

Browse Source 
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).
