Subject: [PATCH] security(phase-9): complete security hardening

- Add safeJsonParse utility with schema validation
- Migrate tokens to OS keyring storage
- Add Ed25519 key encryption at rest
- Enable WSS configuration option
- Fix JSON.parse in HandParamsForm, WorkflowEditor, WorkflowList
- Update test mock data to match valid status values
