Describe this PR

There are two problems here: 1) pedantic_core._pedantic_core.Validation Error: 1 validation error for Settings SENTRY_BACKEND_DSN

It was necessary to add Optional[str]

2) pedantic_or._pedantic_core.Validation Error: 3 validation errors for Connection Config MAIL_USERNAME MAIL_PASSWORD MAIL_SERVER

It should have been changed from None to "" The "ConnectionConfig" class is not optional for pydantic
