### Rationale for this change Invalid sparse tensor indices should be rejected consistently before sparse-to-dense conversion. ### What changes are included in this PR? - Validate sparse index bounds and index tensor buffers. - Validate compressed pointer consistency. - Validate CSF axis ordering. - Check sparse values and dense tensor sizes before conversion. - Keep CSF IPC index buffer sizing consistent with the index element width. ### Are these changes tested? Regression tests were added for invalid CSF axis ordering and out-of-range CSR and CSF indices. C++ formatting and lint checks pass. ### Are there any user-facing changes? Invalid sparse tensor inputs that were previously accepted are now rejected with an `Invalid` status. -- This is an automated message from the Apache Git Service.
