[mrdanish26]

TICKET: WP-8115

Vulnerability identified during the sdk release: https://github.com/BitGo/BitGoJS/actions/runs/22640101489/job/65613574496

Summary

• Upgrade @hashgraph/proto from 2.12.0 to 2.22.0, which drops the
  protobufjs-cli dependency entirely, eliminating the transitive chain
  to the vulnerable [email protected] (CVE-2021-23358, GHSA-qpx9-hpmf-5gmw)
• Bump long from ^4.0.0 to ^5.2.3 to unify on a single version across
  @hashgraph/sdk, @hashgraph/proto, and protobufjs, resolving potential
  instanceof failures from dual Long class versions at runtime
• Update import * as Long from 'long' to import Long from 'long' in 5
  source files for long@5 ESM compatibility (esModuleInterop already enabled)
