feat: optimize Prisma queries by replacing findFirst with findUnique where applicable (#21826)

* feat: optimize Prisma queries by replacing findFirst with findUnique where applicable

- Replace findFirst/findFirstOrThrow with findUnique/findUniqueOrThrow for queries using unique constraints
- Maintain existing functionality and error handling behavior
- Focus on queries using primary keys and unique index fields from schema
- Revert problematic changes that caused test failures to maintain stability

* revert: exclude API files from Prisma query optimizations per user request

- Reverted all 55 API-related files to their original state
- Kept all non-API Prisma query optimizations intact
- API files include apps/api/v1, apps/api/v2, apps/web/app/api, and packages/app-store/*/api
- Non-API optimizations remain for packages/lib, packages/features, apps/web (non-api), etc.
