Merge upstream/master (53 commits) into local

Resolved conflicts:
- ui CompanySettingsSidebar.tsx: keep both Secrets (local) and Cloud upstream (master) nav items
- ui CompanySettingsNav.tsx + test: take master's cloud-upstream/members (drops deprecated `access` tab now consolidated into `members`)
- server plugin-worker-manager.ts: take master's 15min RPC timeout cap
- pnpm-lock.yaml: regenerated via `pnpm install` against merged package.json files
