* fix(e2e/wiki): pass obj_type when deleting wiki nodes in cleanup
The wiki node DELETE endpoint now rejects requests without obj_type
(API error 99992402: "obj_type is required"), causing TestWiki_NodeWorkflow
cleanup to fail on every run. Forward the obj_type from the create/copy
response into the delete query params so cleanup succeeds.
* fix(e2e/wiki): delete cleanup wiki nodes via drive v1 endpoint
The wiki v2 DELETE /spaces/{space_id}/nodes/{node_token} endpoint is
undocumented and rejects requests with `obj_type is required` even when
obj_type is forwarded as a query parameter (see actions run #25005966144).
Switch cleanup to the documented path: delete the underlying drive file
via DELETE /drive/v1/files/{obj_token}?type=<obj_type>, which removes the
backing document and the wiki node in one call.

* fix(e2e/wiki): pass obj_type to wiki delete in body, not query
Previous attempts:
- query (?obj_type=docx) → API still rejects with 99992402 obj_type
required (the wiki delete-node endpoint reads it from the body, not
the query string).
- drive v1 fallback → bot identity does not have drive write scope and
returns 1061004 forbidden, so we cannot reuse drive's delete API for
the cleanup helpers.
