Performance Issue: Cluster Management audit/score/topology api response timeout

### What happened?

I tried to check information about my cluster in Cluster Management, but the audit, score, and topology responses timed out.

### What did you expect to happen?

apis response successfully

### How can we reproduce it (as minimally and precisely as possible)?

import a large Kubernetes cluster and enter into cluster management.

### Anything else we need to know?

I use Postman to get api, topology api use 43.5s and audit api use 38.5s, maybe find some ways to fix this performance issue.
And this is my cluster size:

### Karpor version

v0.4.4

```console
$ karpor -V
# paste output here
```

### OS version

```console
# On Linux:
$ cat /etc/os-release
# paste output here
$ uname -a
# paste output here
alpine Docker

# On Windows:
C:\> wmic os get Caption, Version, BuildNumber, OSArchitecture
# paste output here
```

### Install tools

Helm Chart

Start by reproducing the timeout in Cluster Management on a large Kubernetes cluster, then compare the topology, audit, and score API timings with Postman. Done means these APIs return successfully within an acceptable response time for large clusters; the issue does not name source files or tests to inspect.
