- Previous behavior wa showing a generic API error in the top banner which wasn't ideal UX
- With these changes user is informed about the limitation before performing any action with clear call to upgrade through the billing page
no issue
- The modal only appears when the user hits a limitation trying to activate a custom theme not part of the allowlist (if the custom theme allowlist is configured)
- Changed the upgrade button to green to match the design

- This is first pass on the frontend limit-service integration. Max count queries are substituted with HTTP requests to mimick backend checks. Note, they are not meant to substitute backend checks only to suplment them.
