fix(#344 review F1-F4): test-mock coverage + getSpaces freshness + comment/test fixes

- F1 [blocking]: share-modal.test.tsx + comment-content-view.test.tsx mocked
  page-query without usePageMetaQuery → 3 tests threw (ShareModal uses it
  directly, comment-content-view via MentionContent). Added usePageMetaQuery to
  both mocks (the space-tree mocks were already fixed; these two were missed).
- F2: restored refetchOnMount:true on useGetSpacesQuery — ["spaces"] is
  invalidated only by same-tab mutations (no socket path), so a cross-actor
  change (an admin adding/removing THIS user from a space) left the list stale
  until a hard reload. The other refetchOnMount removals (favorites/watched —
  per-user, same-tab-only gap) stay removed.
- F3: corrected the trash-list + recent-changes KEEP comments — both keys ARE
  invalidated (trash-list by 3 mutations, recent-changes by page CRUD), but
  invalidateQueries only marks an UNMOUNTED query stale without refetching, so the
  mount refetch closes the gap. The old "never invalidated" wording was wrong and
  risked a maintainer deleting a live invalidation as dead code.
- F4: tests for the two load-bearing pure paths — invalidate-on-update-page (the
  undefined-guard: a title-only event keeps the icon; sibling/unrelated subtrees
  untouched) and breadcrumb-path-equal (equal chain → true; any id/slugId/name/
  icon change or length diff → false; both-null → true). Exported
  breadcrumbPathEqual for the test.

Gate: client tsc 0; the 4 affected/new test files 33 passed.

perf(client): cut background re-renders + duplicate work (#344 )

Outside the editor the UI did background work on every tree event, socket
reconnect, and navigation. Tree infra (virtualization/memo/O(N) utils) was
already good — the cost was in the subscriptions and duplicates around it.
Client-only; behavior 1:1.

- Setter-only atom subscriptions → useSetAtom: space-tree-row, use-tree-mutation,
  use-tree-socket no longer subscribe every visible row to the WHOLE treeDataAtom
  value (a tree event re-rendered all ~20-30 rows, bypassing the DocTreeRow memo).
  space-tree-node-menu / mention-list read the tree imperatively (store.get) in
  their handlers only. breadcrumb.tsx uses a selectAtom slice (ancestor chain +
  field equality) instead of the whole-tree subscription.
- Socket handler cleanup (BUG): use-tree-socket + use-query-subscription now
  socket.off() their named handlers on cleanup (were accumulating listeners on
  every reconnect → duplicated invalidations/tree-walks). Mirrors
  use-notification-socket.
- Field-update tree path: invalidateOnUpdatePage does a pointwise patch of the
  cached embed subtrees instead of a blanket invalidatePageTree() (refetch storm);
  structural events keep the blanket invalidate.
- usePageMetaQuery: a content-less select slice for the 13 peripheral subscribers
  that read only title/permissions/id, so they stop re-rendering every ~3s while
  typing / on every collab page.updated (page.tsx keeps the full query for content).
- page.tsx: skeleton + placeholderData keepPreviousData (no blank flash on nav).
- Removed refetchOnMount:true where socket/mutation invalidation already keeps the
  cache fresh (favorite/space/space-watcher/workspace). KEPT it on the 3 queries
  with NO other freshness path (trash-list, created-by, recent-changes) — the
  global default is refetchOnMount:false, so those overrides are load-bearing.
- Small: resize mousemove/up attached only while dragging; per-row emoji-picker
  keydown gated on `opened`; AiChatWindow queries enabled only when the window is
  open.

Gate: client tsc 0, client vitest page+websocket 200 passed (+editor suites),
build ok.
