Fix: failing jenkins load test jobjob

[mutambaraf]

Description

Fixed a failing Jenkins job caused by GraphQL schema mismatches (shortCode on Status type) that were crashing teardown and marking k6 pods as failed despite proposals submitting successfully. Hardened run-cluster.sh with set -euo pipefail, trap-based cleanup, and fixed argument parsing. Updated the webpack build to only bundle the test being run and wired graphql-codegen into lint-staged for automatic type regeneration.

Motivation and Context

The deleteProposal and createProposal mutations were sending a field (shortCode) that no longer exists on the Status type in the live schema, causing an uncaught promise rejection in teardown that k6 treated as a fatal error. The shell script had several silent failure modes (no set -e, negative timeout, broken URL argument parser) that masked errors in CI.

How Has This Been Tested

Fixes

Changes

• run-cluster.sh: fail-fast, trap cleanup, venv activation, fixed arg parser and timeout
• Jenkinsfile.runcluster: boolean params, env block, aligned defaults with shell script
• src/graphql/gql/, generated/: removed shortCode from Status selections, regenerated types against live schema, fixed statusId → workflowStatusId
• webpack.config.js: build only K6_TEST_NAME test, removed target: 'node'
• package.json, .lintstagedrc.json: auto-run codegen on .graphql file changes
