fix: resolve TypeScript linting errors in Phase 3 test files

- Fixed tags format from object array to string array in all test files
- Added type assertions for response.data in get-workflow-details.test.ts
- Added non-null assertions for workflow.nodes in get-workflow.test.ts
- All TypeScript linting errors now resolved
