feat(logging): add Seq transport, global meta fields, and improve error handling

- Add Seq centralized logging transport with async ESM import
- Add appVersion and computerName to logger defaultMeta (all app logs)
- Add appVersion to audit log entries for version-level traceability
- Improve unhandledRejection to capture full stack traces for Error instances
- Add Seq config schema and template configuration
