Unfork NetworkIOAgent.cpp destructor and enableAgent API changes from 0.85 nightly integration

[anuagragith]

Problem Description

During the integration of RN 0.85.0-nightly-20260128-36f07a1b2 (#16245), the upstream NetworkIOAgent API changed from enable()/disable() to enableAgent()/disableAgent(). A destructor was also added to properly clean up the network agent. These changes were applied to the existing override file.

Note: The existing override (tracked by #13587) covers type/namespace fixes. This issue tracks the new destructor and API adaptation.

Current Fix
Updated the existing patched copy at vnext/ReactCommon/TEMP_UntilReactCommonUpdate/jsinspector-modern/NetworkIOAgent.cpp with the destructor and new API calls.
