Adds a server-authoritative whole-tree endpoint and sidebar menu commands
so a deep space tree can be expanded in one request instead of a per-level
BFS storm.
Server:
- POST /pages/tree (SidebarPageTreeDto: spaceId | pageId), same CASL space
scoping as /sidebar-pages. Returns the whole space tree / subtree as a flat
list in the sidebar item shape (id, slugId, title, icon, position,
parentPageId, spaceId, hasChildren, canEdit), ordered by position
(collate C byte order), content never fetched.
- page.service.getSidebarPagesTree reproduces getSidebarPages' two-branch
permission model: open space -> spaceCanEdit; restricted space -> seed the
full descendant set then prune via filterAccessibleTreePages +
filterAccessiblePageIdsWithPermissions (keeps restricted-but-granted pages,
prunes inaccessible subtrees). hasChildren is derived from the final
filtered set so it can never reveal inaccessible children.
- page.repo.getSpaceDescendants: recursive CTE seeded by space roots.
Client:
- SpaceTree is forwardRef exposing expandAll/collapseAll/isExpanding;
expandAll fetches the whole tree once, replaces current-space nodes, opens
every branch (current space only), aborts on space switch, surfaces real
errors; collapseAll collapses only current-space ids (shared open-map).
- SpaceMenu gains Expand all / Collapse all items (no admin gate).
Implements docs/backlog/tree-expand-collapse-all.md.
