Simplify build.sh and update run.sh for self-contained execution

- Simplified build.sh to just build in release mode with warning suppression
- Updated run.sh to build first, then start supervisor and admin UI together
- Run script now starts both supervisor API and admin UI in background
- Added proper cleanup handler for graceful shutdown
- Removed admin UI compilation errors by fixing JsValue handling
- Added list_jobs method to WASM client for admin UI compatibility
