build image log fix

[giurgiur99]

Fixes # .

Changes proposed in this PR:

BuildImage builds its log file path from tempFolder instead of getStoragePath() (which is tempFolder + clusterHash). The job folder is created under getStoragePath(), so writes target a non-existent directory.

Fix

• buildImage: use getStoragePath() for imageLogFile. Aligns with pullImage.
• buildImage.test.ts: mkdirSync updated to match.

Summary:
This PR updates the C2D Docker engine to correctly resolve the image.log file path using getStoragePath() rather than a hardcoded reference to tempFolder. The unit tests have been updated accordingly to mirror this logic. Overall, the logic is sound and correctly addresses path resolution inconsistencies. LGTM!

Comments:
• [INFO][style] Consider using path.join instead of string concatenation for constructing file paths. This ensures better cross-platform compatibility and avoids subtle bugs with missing or duplicate directory separators.

-    const imageLogFile = this.getStoragePath() + '/' + job.jobId + '/data/logs/image.log'
+    const imageLogFile = path.join(this.getStoragePath(), job.jobId, 'data', 'logs', 'image.log')

(Ensure path is imported at the top of the file if you apply this change).
• [INFO][other] Good job dynamically fetching the expected storage path from the engine instance rather than hardcoding the temp folder. This keeps the test robust against future underlying path logic changes.
