Update config: add pipe delimiter and reorder blocks

- Change delimiter from " " to " | " for better spacing
- Reorder blocks for correct right-to-left display
- Remove sb-help-icon

Replace sb-playerctl with sb-dashboard block

Switch to dwmblocks-async for better performance

Async version prevents slow scripts from blocking status bar.
