fix: Multiple Command Center improvements

LISTINGS PAGE:
- Added missing Sparkles import

PORTFOLIO PAGE:
- Changed dropdown menu to open downward (top-full mt-1)
  instead of upward for better visibility

SEO PAGE:
- Added cleanDomain() helper to sanitize input
- Removes whitespace, protocol, www, and trailing slashes
- Fixes 'hushen. app' -> 'hushen.app' input issue

PRICING PAGE:
- Removed accent highlight from 'TLDs Tracked' StatCard

All StatCards now have consistent styling without
green accent highlights.
