Fix: Synchronize SvelteKit relay and enhance native command testing

- Updated electron_relay.ts with full Phase 3 command set (run_cmd_sync, kill_processes, get_device_info).
- Fixed 500 error in Event Location by standardizing enabled/hidden flags.
- Hardened native environment detection in root layout.
- Added Manual OS Command input to Launcher Configuration for Phase 3 testing.
