fix: add CmsBaseUrl/FrontOfficeBaseUrl to appsettings.json for staging callback URLs

- Added CmsBaseUrl=https://cms.se.kbs1.ir to appsettings.json
- Added FrontOfficeBaseUrl=https://foursat.se.kbs1.ir to appsettings.json
- Fixed PurchasePackageCommandHandler hardcoded yourdomain.com
- Development keeps localhost values via appsettings.Development.json
