Bug description:
  [ Impact ]

   * Horizon currently uses client-side filtering for the volumes and 
     snapshots tables.When pagnation is enabled, this results in filtering 
     being applied to only the items visible on the current page rather
     than across the full dataset.

   * In environments with many volumes or snapshots, this results in users 
     being unable to locate resources via the filter unless they manually 
     navigate to the correct page, leading to confusion and degraded usability.

   * Backporting this fix improves the Horizon user experience by ensuring 
     filtering is applied across the entire dataset.

   * The uploaded fix switches filtering to the server side using the Cinder API, 
     which supports filtering in combination with pagination.

  [ Test Plan ]

   * [0] The following versions of Ubuntu-OpenStack will be tested:
         - UCA: jammy-caracal
         - UCA: noble-dalmatian
         - UCA: noble-epoxy
         - UCA: noble-flamingo
         - ubuntu: noble-caracal
         - ubuntu: questing-flamingo

    * [1] Deploy an OpenStack environment on the target series.

    * [2] Log into the Horizon dashboard.

    * [3] Ensure there are enough volumes/snapshots to span multiple pages.
          This can be done easily by changing the number of items displayed 
          per page to something like '5' in the user settings.

          Then create 10 volumes
            for i in $(seq -w 1 10); do
            openstack volume create --size 1 vol-$i
            done
          
          And create 10 snapshots
            for i in $(seq -w 1 10); do
            openstack volume snapshot create --volume vol-$i snap-$i
            done

    * [4] While on page 1, search for a volume/snapshot name into the filter
          box that is not on the first page.

    * [5] Verify the behavior- Before the patch, the volume/snapshot will not
          be shown because it is not on the first page. After the patch is 
          applied, the volume/snapshot should be shown when searched for.

  [ Where problems could occur ]

   * This change replaces client-side filtering logic with server side filtering 
     via the Cinder API. If the deployed Cinder API does not support the expected
     filtering parameters, filtering may fail.

  [ Other Info ]

   * Upstream commit to horizon (master):
     https://review.opendev.org/c/openstack/horizon/+/963468

   * Known workaround: Increase the number of results that appear on a page so you
     don't have to go through as many pages when searching for a volume/snapshot.
