statistics: add Destroy method and handle session recycling

[0xPoe]

What problem does this PR solve?

Issue Number: close #59524 close #59560

Problem Summary:

What changed and how does it work?

ref #59522

This is an alternative API design to solve the problem. I believe explicitly using destroy instead of exposing implementation details is a better approach to fix it.

I also added more logs to help us inspect error cases.

Note: This PR doesn’t address the root cause of the issues; it only ensures that we don’t encounter OOM problems. We still need to figure out why we’re running into this kind of stats loading.
