HDDS-15007. SCM Web UI search box should filter the entire datanodes set, not just the displayed rows

Implemented globalSearch for Node Status Search bar.
'HDDS-15007. SCM Web UI search box should filter the entire datanodes set, not just the displayed rows '

In the existing design, the search box on the SCM Web UI "Node Status" table had a page-level filter where we could only search across the currently visible rows governed by 'Show' dropdown (e.g., 10 ,20, 50 , All nodes at a time). Finding a specific datanode in a large cluster requires :
1: Either change the 'Show' dropdown to have more records in the table manually + search -> If target match found Ok else clicking through multiple pages in (previous - next ) fashion until the target node appeared on the active page.
2: Keep searching on the table with default size 10

Proposed Changes:
This PR introduces a global search mechanism to the SCM Web UI. The search input now filters against the entire master dataset of datanodes before the pagination slicing occurs, allowing users to instantly find nodes regardless of which page they originally resided on. Also it shows the pagination .

How was this patch tested?

• **Validated the existing implementation first **

-> page-1

-> page-2

-> Search "ozone-ha-datanode-7.ozone-ha_default" UUID on serach bar at Page-1

If we could have search on page-2, we have the target match , and since have one more records on 3rd page next navigation is enable.

• Validated Proposed Implementation

Scaled the cluster to 21 datanodes using docker-compose up --scale datanode=21 to force multiple pages of records.
Navigated to Page 1 and searched for a datanode known to be located on Page 2. Verified that the node immediately appeared in the table. Verified that the pagination text dynamically updated to reflect the search results (e.g., "Showing 1 to 1 of the total 1 entries.") and that the Next/Previous buttons disabled appropriately to prevent navigating to empty pages.
Cleared the search box and verified that the table restored the full cluster view and correct pagination.

-> page-1

-> page-2 (taken ozone-ha-datanode-19.ozone-ha_default for global serach)

-> page-3

-> global serach found! (ozone-ha-datanode-19.ozone-ha_default -found)

-> prev, next navigation disabled
