⬆️ Fix custom settings class with pydantic-settings~=2.6

[pcrespov]

What do these changes do?

The upgrade to pydantic-settings~=2.6 disrupted the auto_default_from_env mechanism. This PR introduces a solution:

• 🎨 Adds EnvSettingsWithAutoDefaultSource, a new settings source that executes the default factory injected upon construction of the class (see __pydantic_init_subclass__).
• ✅ Includes additional tests for robust coverage.
• 🐛 Corrects import errors in the catalog.
• Updates latest pydatnci-settings everywhere

• Part of Major upgrade to pydantic 2.0 #4481
