Add query cache utilities for campaign data invalidation

Introduce new functions in query-cache.ts to handle cache invalidation for campaign-related queries. Update CampaignDetailPage, CampaignsPage, and CampaignWizardPage to utilize these functions for improved cache management upon successful mutations, ensuring the UI reflects the latest campaign data.
