Improve subscription dialog width for laptop screens (#7324)

## Summary
- Increase Stripe subscription dialog width for better experience on
laptop screens

When too narrow, it forces pricing options grid to go into single column
layout which looks bad and should only happen when absolutely necessary
(e.g,. mobile viewport).
