fix(queries): fix index for expiration job

[jiparis]

This query is not ordered, so the index cannot be used directly. Instead, Postgresql was partially using a different index (workflowrun_state_finished_at), and then filtering by creating_at, adding an additional performance penalization.

Limit  (cost=0.29..6.07 rows=1 width=250) (actual time=0.133..0.134 rows=0 loops=1)
  ->  Index Scan using workflowrun_state_finished_at on workflow_runs  (cost=0.29..6.07 rows=1 width=250) (actual time=0.131..0.132 rows=0 loops=1)
        Index Cond: ((state)::text = 'initialized'::text)
        Filter: (created_at <= '2025-06-25 11:42:12.793517+00'::timestamp with time zone)
Planning Time: 1.043 ms
Execution Time: 0.245 ms

With the fixed index, the query is fully optimized:

Limit  (cost=0.29..8.31 rows=1 width=249) (actual time=0.056..0.056 rows=0 loops=1)
  ->  Index Scan using workflowrun_state_created_at on workflow_runs  (cost=0.29..8.31 rows=1 width=249) (actual time=0.055..0.055 rows=0 loops=1)
        Index Cond: (((state)::text = 'initialized'::text) AND (created_at <= '2025-06-25 11:42:12.793517+00'::timestamp with time zone))
Planning Time: 0.674 ms
Execution Time: 0.099 ms
