[#1094][FIX] alerts: skip owner override when alert_owner_id is in updates

[Romil2112]

Summary

Fixes #1094.

When alerts_batch_update_route processes an alert with alert_owner_id = NULL, it unconditionally falls back to current_user.id, ignoring any alert_owner_id the caller explicitly included in the payload. This causes the first Assign → [user] action on an ownerless alert to behave identically to Assign to me, requiring a second identical request to apply the intended owner.

The fix adds a guard so the fallback only fires when the caller did not supply an alert_owner_id:

# before
if alert.alert_owner_id is None:
    updates['alert_owner_id'] = iris_current_user.id

# after
if alert.alert_owner_id is None and 'alert_owner_id' not in updates:
    updates['alert_owner_id'] = iris_current_user.id

Test plan

• Batch-assign an ownerless alert to a user other than the logged-in user; verify it is assigned to the intended user on the first attempt
• Batch-assign an ownerless alert with no alert_owner_id in the payload (e.g. a status-only update); verify it still falls back to the current user
• Verify existing batch-update flows (status change, severity change) are unaffected
