[NSPF-459621] MAGc - Revert and Rebalance Automation

Release introduced: 25.4

NSP workflow will execute either revert or rebalance on MAGc node based on the event notification type sent by the node. These actions help in distributing subscriber sessions among all active/backup MAGu's connected to a given MAGc.

- Revert Operation: While the number of available UPF connections in the primary list of the target profile was below the minimum threshold, new sessions can now be reverted back from backup UPFs to primary UPFs.​

- ​Rebalance Operation: The system has reconnected to a UPF after having been disconnected, which requires rebalancing of sessions among the available UPFs in the primary list of the target profile.
