Align command metadata consistently in the slash-command menu

Summary

Command names have different widths, causing command titles and descriptions to begin at inconsistent horizontal positions.

This makes the command list look uneven and reduces scanability.

Affected areas

• Slash-command menu
• Command name badges
• Command titles and descriptions
• Responsive layouts

Current behavior

Each command name badge uses its natural content width.

Long command names push their title and description farther to the right, while short names place the same content closer to the left.

Expected behavior

Command rows should use a consistent column layout so titles and descriptions align vertically.

On narrow screens, the layout should switch to a readable stacked arrangement instead of truncating or overflowing important content.
