Quarantined server tests: workflows (18 tests) — CI gate rehab

Part of the CI gate rollout: these tests fail on current main-era code and are quarantined (it.skip with a QUARANTINE tag) so the run-ci Gate can be fully blocking. Fix and un-skip sprint-wise.

Context: server test suite ported from lts (#15740) to main; failures are drift against evolved product code or specs added while main CI was down. Baseline run: https://github.com/ToolJet/ToolJet/actions/runs/29853452911

Quarantined tests

• test/modules/workflows/e2e/external-api-groups.e2e-spec.ts — downgrade: deletes canEdit=true entry, migrates its resources into canEdit=false entry
• test/modules/workflows/e2e/workflow-executions.spec.ts — should access state variables in runpy node
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute a simple workflow with start trigger and response
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with both RunJS and RunPy nodes using their respective bundles
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with Python bundle using pydash
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with Python setup script using numpy
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with REST API query node
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with REST API query using NPM packages in template expressions
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with RunJS query node
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with RunPy query node
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with setup script but NO NPM dependencies
• test/modules/workflows/e2e/workflow-executions.spec.ts — should execute workflow with setup script using lodash
• test/modules/workflows/e2e/workflow-executions.spec.ts — should list all executions for an app version
• test/modules/workflows/e2e/workflow-executions.spec.ts — should retrieve execution nodes with pagination
• test/modules/workflows/e2e/workflow-executions.spec.ts — should retrieve paginated execution logs
• test/modules/workflows/e2e/workflow-executions.spec.ts — should retrieve workflow execution details including logs
• test/modules/workflows/e2e/workflow-executions.spec.ts — should retrieve workflow execution status
• test/modules/workflows/e2e/workflow-webhook.spec.ts — should return 429 when webhook trigger rate limit is exceeded
