fix: BIOS update only when newer, device check first, aligned warnings

- Greyed out and not tickable unless Valve has a newer BIOS (component_selectable).
- Download, SHA-256 and a fwupd device check (get-details) before the warnings.
- Warning box with a solid block frame (a coloured row of # renders narrower in Konsole); menu Now column aligned.
