…ns (canonical#280) When an IP is allocated inside a dynamic range reservation, the validation performed during a resize sees the range as discontinuous, since an allocated IP splits the available space into separate contiguous blocks. As a result, both shrinking and expanding the reservation are rejected with "Requested dynamic range conflicts with an existing IP address or range", even when the requested change is otherwise valid. This commit addresses the issue by comparing the requested range against the previously persisted range and requiring only the newly added segments (i.e., the expanded portions) to be contained within an unused range. Pure shrinks add no segments and are always allowed. Resolves LP:2143090
