Code Review

This pull request bumps dependency versions across multiple Google Cloud Java libraries. Key functional updates include adding support for Postgres 19 in AlloyDB, and introducing a new GetHealth operation for ReservationSlots in the Compute client. The Compute client also receives updates for Bare Metal Secure AI (BMSAI) confidential compute types, a new SUSPEND_SAFE_FPR guest OS feature, a self_link_with_id field in Interconnect, a target_status field in ManagedInstance, a GCE_VM_IP_DEDICATED_BACKEND network endpoint type, new ARP broadcast subnet mask resolution options, and new bandwidth fields in InterconnectLocationCrossSiteInterconnectInfo. There are no review comments to address, and I have no additional feedback to provide.
