Add Workflow archive lifecycle

[AbigailDeng]

Problem

Published Workflows had no Archive action, so operators could not stop new runs without losing the distinction between an editable draft and a published deployment. The default catalogue also had no archived view.

Solution

• Add Archive only for active published Workflows with an authoritative deployment identity.
• Map Archive to deployment deactivation and wait for the Workflow list to report Deactivated before showing success.
• Preserve drafts, published revisions, and Activity history.
• Keep archived Workflows out of the default Active view and expose them in an Archived view.
• Retry observation without resubmitting an accepted deactivation command; retry the command only when acceptance failed.
• Keep Delete draft limited to Workflows with editable draft membership.

Impact

• Workflow Activity vNext catalogue filtering, status, actions, and confirmation UI
• English and Chinese Workflow catalogue messages
• Focused archival observation and interaction tests
• Product design and implementation documentation

Local verification

• Related and changed tests: pnpm exec jest --runInBand --runTestsByPath src/pages/workflow-activity-vnext/workflows/workflowArchival.test.ts src/pages/workflow-activity-vnext/index.test.tsx - 2 suites, 93 tests passed
• Changed-file static checks: pnpm exec biome check src/locales/workflowActivityVNextMessages.en-US.ts src/locales/workflowActivityVNextMessages.zh-CN.ts src/pages/workflow-activity-vnext/index.test.tsx src/pages/workflow-activity-vnext/styles.ts src/pages/workflow-activity-vnext/workflows/WorkflowsPage.tsx src/pages/workflow-activity-vnext/workflows/workflowArchival.test.ts src/pages/workflow-activity-vnext/workflows/workflowArchival.ts - passed
• Test stability guard: bash tools/ci/test_stability_guards.sh - passed
• Documentation lint: bash tools/docs/lint.sh - passed
• Whitespace validation: git diff --check - passed
• A reliable affected typecheck target is unavailable, so local typecheck was skipped.
• Full frontend suite/typecheck/build: deferred to GitHub CI by personal local workflow policy

Conflict resolution verification

Merged the latest feat/2026-08-04_workflow-activity-vnext into this branch and resolved the Workflow catalogue action-menu conflict. The merged menu preserves the base branch action hierarchy and exposes Delete draft and Archive according to their independent eligibility rules.

• Related-test dry run: pnpm exec jest --listTests --findRelatedTests src/pages/workflow-activity-vnext/workflows/WorkflowsPage.tsx src/pages/workflow-activity-vnext/workflows/workflowArchival.ts - resolved only index.test.tsx and workflowArchival.test.ts
• Catalogue tests: pnpm exec jest --runInBand --runTestsByPath src/pages/workflow-activity-vnext/index.test.tsx -t "Workflow Activity vNext catalogue" - 22 passed
• Archival helper tests: pnpm exec jest --runInBand --runTestsByPath src/pages/workflow-activity-vnext/workflows/workflowArchival.test.ts - 5 passed
• Changed-file static checks: pnpm exec biome check with the 7 PR frontend files - passed
• Test stability guard: bash tools/ci/test_stability_guards.sh - passed
• Documentation lint: bash tools/docs/lint.sh - passed
• Whitespace validation: git diff --check and git diff --cached --check - passed
• Full frontend suite/typecheck/build: deferred to GitHub CI by personal local workflow policy
