Summary

• add a dedicated creator list sort mapper for translating allowed public sort values into internal query behavior
• centralize allowed creator list sort options and sort orders in one reusable module
• update creator list schema validation to use the shared sort constants
• stop passing the public sort value directly into Prisma orderBy

Testing

• corepack pnpm lint
• corepack pnpm exec prettier --write src/modules/creators/creators.sort.ts src/modules/creators/creators.schemas.ts src/modules/creators/creators.utils.ts

Notes

• corepack pnpm build is currently blocked by Prisma client generation/type availability in the repo environment, including existing errors in unrelated files outside this change
• corepack pnpm generate hung locally instead of completing, so full build validation could not be completed here

Closes #33
