Add "Contains" and "Does Not Contain" operators for Mgmt IP in Dynamic Search

Dynamic Search for the Mgmt IP field currently does not offer a 'Contains' or 'Does Not Contain' operator, limiting users to exact-match style criteria when building Dynamic Device Groups. This enhancement would add 'Contains' and 'Does Not Contain' as selectable operators for the Mgmt IP field in Dynamic Search. Customers managing devices across specific IP ranges or subnets would be able to group devices by partial IP address matches without needing to manually enumerate each address or rely on workarounds.
