Improve 24h task UI readability

[beck-8]

Neither the history table nor the current page can tell me exactly if there are really completely failed tasks. That's why I have this idea.

Expect similar changes

Task	Tasks	Succeeded	Failed	Recovered
SendTransaction	521	516	3 (0.58%)	2
PDPv0_ProvPeriod	216	210	0	6
PDPv0_Prove	210	203	3 (1.43%)	4
StorageGCMark	160	159	0	0 (1 pending)

Rough plan

CREATE INDEX harmony_task_history_recent_task_result_idx
ON harmony_task_history (work_end DESC, task_id ASC, result ASC);

SELECT
    COUNT(DISTINCT task_id) FILTER (WHERE has_success) AS succeeded_tasks,
    COUNT(DISTINCT task_id) FILTER (WHERE NOT has_success) AS failed_only_tasks
FROM (
    SELECT
        task_id,
        BOOL_OR(result) AS has_success
    FROM harmony_task_history
    WHERE work_end >= NOW() - INTERVAL '24 hours'
    GROUP BY task_id
) t;

I assume this is a good to have but not needed for FOC GA. Please correct if that is wrong.

Yes, this is not required for GA but a nice to have.
