TSDB status endpoint limited to 10,000 statistics sets preventing OOM

How to detect:
v3.9.0 adds a maximum limit of 10,000 sets of statistics to the TSDB status API endpoint to prevent out-of-memory conditions when querying instances with extremely high cardinality. Queries requesting more than 10,000 statistics sets will be truncated.
Recommended action:
Review any automation or dashboards calling /api/v1/status/tsdb endpoint. Verify they handle truncated responses appropriately when statistics exceed 10,000 sets. For high-cardinality environments, consider using more specific label matchers to reduce result set size or paginating requests if comprehensive statistics are required.
