fix: update annotation source when label category changes

[Joshuathomas18]

Summary

Previously, changing the label of automatically or semi-automatically annotated objects did not update their corresponding source field (AUTO / SEMI-AUTO).
This caused inconsistencies in annotation metadata, particularly when reassigning labels post-automation.

This PR adds conditional logic in updateAnnotationsAsync() to correctly set the source whenever the label_id changes.

---

Motivation and Context

This change ensures that annotations remain consistent and traceable even after label modifications.
Maintaining accurate source values is important for:

• Differentiating manual and automated annotations in dataset exports.
• Ensuring correct analytics on annotation methods.
• Avoiding data drift in semi-automated pipelines.

---

Implementation Details

• Added a label change check inside updateAnnotationsAsync().
• When label_id changes, the function now updates the source to:
  • MANUAL if modified manually,
  • Retains AUTO or SEMI-AUTO only when automation still applies.
• Added inline comments for future maintainability.

---

How Has This Been Tested?

• Verified in the annotation UI that label changes correctly update source.
• Tested both AUTO and SEMI-AUTO annotation types.
• Confirmed the update persists in task exports and the REST API response.
• No regressions found in manual annotation flow.
