refactor: polish MCP/LSP settings and activity panel UI

- Use indigo accent consistently instead of blue for toggle states
- Replace bulky toggle cards with compact toggle switches in Activity panel
- Fix input focus states to use app-standard indigo glow
- Use semantic nav icons: Server for MCP, Code for LSP
- Style Save button with indigo primary, Delete with subtle destructive hover
- Add Info icon to callout hints
- Center empty states, clean up list item detail text
- Fix indentation in App.tsx settings overlay wiring
