Add support for a tool/API that allows attaching image files (e.g., PNG, JPEG) to test cases or test results #1064

Description
Currently, there is no direct way to attach image-based test results (such as .png, .jpeg, etc.) to test cases using the available tools in this repository. This limits the ability to include visual evidence for test execution, which is especially useful for UI testing and debugging.

Proposed Enhancement
Add support for a tool/API that allows attaching image files (e.g., PNG, JPEG) to test cases or test results.

Use Case
In many testing workflows (particularly UI/automation testing), capturing screenshots is essential for:

Documenting test execution results
Highlighting visual defects
Providing evidence for passed/failed scenarios

Being able to programmatically attach these images to test cases would:

Improve traceability
Enhance debugging efficiency
Provide better reporting and auditability

Suggested Functionality

Allow upload of image files (.png, .jpg, .jpeg, etc.)
Associate attachments with:
Test cases
Test runs
Test results
Support attaching files via API/tooling in automated pipelines

Example Scenario

Automated UI test runs
Screenshot captured on failure (or success)
Tool uploads and attaches the screenshot to the corresponding test result/test case

Expected Outcome
A seamless way to include visual artifacts in test management workflows, improving overall usability and reporting quality.
