@W-23870895: Document allData behavior

[sf-ali-mahmoud]

Description

Documents the version-specific get-view-data contract: legacy CSV/S3 behavior below Tableau REST API 3.30 and structured allData multipart results on 3.30 and later. Updates the tool index to remove the obsolete first-dashboard-worksheet limitation for the allData path.

Motivation and Context

W-23870895 documents the allData behavior shipped by #831 and covered by #877. Its previous acceptance criteria described an abandoned client-side sheet-selection design; the work item is now aligned with the implementation stories in the same epic.
