BTM- Update UI/UX

[PazYanoverr]

After handling https://github.com/amplication/amplication/issues/8546, we would like to update the BTM UI/UX to-

1. Remove the BTM button from the Project Overview screen
2. Remove the BTM button from the Service Overview & Service Entities screens
3. Leave only the "AI helper" button in the Project --> Architecture tab, and update its name to "Break the Monolith"

Failed on Sandbox-
#1 and #2 work as expected.
In #3- the name of the button was not updated to "Break the Monolith"
