🎨 Palette: Center align TUI help footer

[EffortlessSteven]

💡 What: Added .alignment(Alignment::Center) to the TUI help footer widget.
🎯 Why: Center-aligning the secondary help text at the bottom creates a clearer visual hierarchy, distinguishing it from left-aligned main content and making the interface feel more balanced and intentional.
📸 Before/After: Not applicable (terminal interface).
♿ Accessibility: No structural accessibility changes, but visual hierarchy improves overall cognitive load for sighted users.
