fix(gold): resolve task_status_intervals name collision

[aleksdotbar]

The dbt gold model task_status_intervals (materialized=table) and the refreshable materialized view of the same name from migrations 20260429/20260708 both target insight.task_status_intervals. The gold build runs after migrations in the deploy hook, so dbt replaces the MV with a MergeTree table; a later migration run then executes DROP VIEW IF EXISTS task_status_intervals against a non-view and fails with code 80 (... is not a View), failing the post-upgrade hook.

Rename the dbt model and its alias to task_status_spans. The sibling task_issue_state already uses a name distinct from its MV counterpart task_issue_current_state; the intervals model missed the same treatment. Migrations are unchanged.

Validated with dbt parse (clean) and dbt ls: task_status_spans+ resolves task_metric_observations, and task_status_intervals no longer matches any node.
