[Improved, Fixed] Indeed sponsored campaigns hotfix

Improvements

• Classet now stays in sync with Indeed even when the job-source data comes back in unexpected formats, reducing the chance of future campaign sync errors.

Fixes

• Fixed a problem that hid the sponsored campaign status card; campaign budget and status now appear immediately after a job is sponsored on Indeed.
• Restored automatic bonus-credit attribution for sponsored jobs so available credits are applied correctly.
• Corrected an issue that sometimes prevented campaign data from being cached, which could make sponsored jobs disappear after refreshing the page.
