Defined in:
app/services/generated_image_importer.rb

Overview

Promotes a pending +GeneratedImage+ into a permanent +Image+ library record
and executes any source-record side effects (e.g. back-filling avatar IDs).

Extracted from +GeneratedImagesController+ so background workers can perform
the same operation without going through a controller action.

Usage:
result = GeneratedImageImporter.call(generated_image, title: "...", tags: [...])
result.success? # => true
result.image # => Image record
result.notice # => flash-ready string
