"Validation error in TestResultDBRowSchema: severity 'none' is not an allowed value"

[yu-iskw]

Describe the bug
When running edr report command, it fails with a validation error indicating that the severity field in TestResultDBRowSchema contains the value "none", which is not allowed.

To Reproduce
Steps to reproduce the behavior:

1. run dbt build with dbt Fusio
2. Run edr report
3. See validation error

Expected behavior
The elementary report should generate successfully without validation errors.

N/A

Environment (please complete the following information):

• Elementary CLI (edr) version: 0.20.1
• Elementary dbt package version: 0.20.1 (found in packages.yml file)
• dbt version you're using: dbt-fusion 2.0.0-preview.92
• Data warehouse: BigQuery
• Infrastructure details: macOS darwin 24.6.0, development environment, local deployment

Additional context
Full error message:

ERROR — Could not generate the report - Error: 1 validation error for TestResultDBRowSchema
severity
  none is not an allowed value (type=type_error.none.not_allowed)

The error occurs in the TestResultDBRowSchema validation when processing test results data. This appears to be a schema validation issue where the severity field is returning "none" instead of an expected enumerated value.

Would you be willing to contribute a fix for this issue?
I would be willing to help test a fix but would need guidance on contributing code changes.
