Description

Total number of simulations isn't updated when one is deleted in the simulation screen or in the scenarios screen

Environment

1. MacOS
2. OpenBAS version: 1.11.0
3. OpenBAS client: frontend

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Go to the simulations screen
2. Add multiple new simulations
3. Delete a few simulations

Expected Output

The total number of simulations should be updated live

Actual Output

The total number of simulations stays the same after a delete. A manual refresh is necessary.

Expected output: When deleting a simulation, the total number of simulations should be updated in the top right corner of the pagination.

@guillaumejparis should be fix by branching our pagination system to the store
