mgr/prometheus: fix pool_objects_repaired and daemon_health_metrics format

- fix "error reading metrics for http://****:***/metrics: reading text format failed: text format parsing error in line 2010: second HELP line for metric name "ceph_pool_objects_repaired" error

- rename label name "poolid" to "pool_id" like all other metrics
- change type for the "daemon_health_metrics" to gauge

Fixes: https://tracker.ceph.com/issues/59505
