fix: add take limits on media includes and enforce pagination validation

- Add take: 10 on unbounded media include in findByIdWithProperty
- Add take: 100 + orderBy on user listings include in getUserDetail
- Convert GetUsersQueryDto page/limit from string to validated integers with @Min(1) @Max(100)
- Add @Max(100) to BillingHistoryParamsDto limit field
- Refactor admin controller to use GetUsersQueryDto with class-validator pipeline
