Fixes security vulnerability: gRPC-Go authorization bypass via missing leading slash in :path pseudo-header. This is an authorization bypass resulting from improper input validation that allows attackers to bypass path-based authorization policies. CVE fix recommended upgrade from v1.79.1 to v1.79.3.

Summary
This PR upgrades
google.golang.org/grpcfrom v1.79.1 to v1.79.3 to fix a security vulnerability.Vulnerability Details
Type: Authorization Bypass via Improper Input Validation
The gRPC-Go server was accepting requests where the
:pathHTTP/2 pseudo-header omitted the mandatory leading slash (e.g.,Service/Methodinstead of/Service/Method). While the server correctly routed these requests, authorization interceptors evaluated the raw, non-canonical path string. This allowed "deny" rules defined using canonical paths to be bypassed.Impact
This affects gRPC-Go servers that:
Fix

:pathnot starting with a leading slash is immediately rejected with acodes.Unimplementederror.Changes
