Description

Fixed an issue where running c4 host reserve without specifying any reserved addresses incorrectly reported success if the deployment already had previously reserved addresses saved in its configuration.

Workaround

No workaround.

Fix

Updated the validation to check only the addresses explicitly provided in the current command invocation, ensuring the command fails with an error when no reserved addresses are supplied, instead of silently using stale values from previous reservations.
