feat: settings UI

[tnunamak]

This makes it more feasible to use non-local models. For local models, it includes a significant performance improvement by keeping the loaded model in memory which removes the majority of the latency (for Apple silicon, at least). Other changes:

• Automatically start the service when the system trap app is launched.
• Simplify Playground search UI to make it more approachable
• Banner on the Playground page directing new users to add data
• Style relevant rjsf components with daisy styles for a consistent look and feel
