Enatega Admin-dashboard: Change success message content when new store is added

### Describe the bug
This bug involves the success message displayed when a new store is added. Instead of showing the correct confirmation message, the system either displays incorrect, misleading, or generic text that does not accurately confirm the action taken. It is currently displaying a message Timing Updated.

### To Reproduce
Steps to reproduce the behavior:

1. Navigate to the store creation page.
2. Enter the required details and submit the form.
3. Observe the success message displayed.

### Expected behavior
It should display a message '' New store added or created successfully''

Desktop (please complete the following information):

> OS: [e.g. Windows]
> Browser [e.g. Chrome]
> Version [e.g. Latest]

Start at the admin dashboard's store creation page and search the frontend for the current “Timing Updated” success text. Change the message shown after a store is submitted to confirm that the new store was added or created successfully, then reproduce the steps in the issue to verify the result.
