Greptile Summary

This PR switches all 7 SAP S/4HANA update tools from PATCH to MERGE for better OData v2 compatibility with legacy SAP gateways, and tightens the SapS4HanaIcon viewBox to make the logo render larger in block tiles. The proxy (route.ts) already had MERGE in its HttpMethod enum and WRITE_METHODS set prior to this PR, so no server-side changes were required — the tools simply weren't using the supported method.

Confidence Score: 4/5

Safe to merge — targeted, low-risk changes with full proxy-layer support already in place

All 7 tool changes are identical one-liners; the proxy already accepted MERGE before this PR. The viewBox crop is a straightforward visual adjustment mirrored correctly in both icon files. No automated tests were added (checkbox unchecked), keeping this below a perfect 5.

No files require special attention
