feat(lookup): enhance lookup functionality to support CIDR queries

Updated the lookup system to allow for CIDR queries in addition to IP and domain searches. This includes modifications to the API, frontend components, and documentation to reflect the new capabilities. The LookupSearchForm and LookupComponent were adjusted to accommodate CIDR input, and relevant tests were added to ensure functionality.
