Introduce internal/repository for data access and cache-backed system config reads. Move business logic into logics.go across admin push, user, template, cache, system_config, and upload/handler packages. Remove Gin from internal/util by relocating request-scoped helpers to oauth/gin_context.go. Propagate request context for config lookups in user flows. Slim model entities and delete model-level DB/cache helpers. Wire handlers to logics/repository so targeted packages no longer call db.DB directly. Update admin router tests to use ErrorHandlerMiddleware.
