feat(notebook): load notebook space via token and pre-select docs/sources

- NotebookAIWritingPage reads `token` from URL, fetches space data from
  notebook-token API (search_space_id, doc_ids, user_token) and space
  name from searchspaces API; keep-alive ping every 50s resets Redis TTL
- Pass user_token as studioToken through AIWritingPage → AIWritingLayout
  → WritingFormPanel → AIWritingPanel → AIWritingForm to skip
  getTokenByEmail when studio token is already available
- useStudioNotebooks accepts enabled flag; useNotebookSources accepts
  overrideToken to bypass the internal token fetch
- AIWritingForm hides notebook selector when studioToken is provided
  (notebook is pre-locked) and pre-selects initialDocumentIds
