Remove the ability to modify predefined sources in the Customer Cards Configuration

[Amygos]

It may make sense to remove the ability to modify or delete predefined sources in the "Customer Cards Configuration" to prevent users from making changes that could cause damage, such as changing passwords or modifying other critical settings.

Currently, users can modify or delete the predefined sources such as:

• phonebook (MySQL)
• asteriskcdrdb (MySQL)

By removing this capability, we can ensure more control over essential data sources and prevent potential issues.
