Warning Alert for Decreased Node License Count During License Refresh

NetBrain currently does not notify administrators when the node license count decreases as a result of a license refresh, leaving the change undetected until it affects device monitoring capacity. This enhancement would display a warning message to the user at the time of refresh whenever the node license count has decreased compared to its prior value. Providing this visibility would allow administrators to promptly investigate license changes and adjust node allocations before capacity issues impact operations.
