creator-mapping

[Daniel-Ric]

Motivation

• Inventory creator counts were returning raw IDs or unknown because entitlements only contained creator IDs and not display names, so clients could not show human-friendly creator names.

Description

• Add a creatorLookup parameter to summarizeCreators in src/utils/inventoryCreators.js so resolved creator identifiers can be mapped to display names.
• Resolve marketplace creators via getCreators and build an ID→displayName lookup in src/routes/inventory.routes.js and src/routes/purchase.routes.js, then pass that lookup into summarizeCreators.
• Update OpenAPI docs in src/utils/swagger.js and the README to indicate creators are grouped by display name and add an example GET /inventory/creators curl line.
• Add a unit test in test/inventoryCreators.test.js that verifies mapping of creator IDs to display names.

Testing

• Ran the test suite with npm test and all tests passed: 3 tests, 0 failures.
