#367 fix(clerk): remove unnecessary domain and isSatellite props

Summary

• Removes domain and isSatellite props from ClerkProvider in web, marketing, and admin apps
• Fixes malformed Clerk URL (clerk..superset.sh) that was causing sign-in page to fail in production
• These props are only needed for satellite domain setups, which we don't use

Test plan

• Verify sign-in page loads without errors on web app
• Verify marketing site auth still works
• Verify admin dashboard auth still works
