BUG: Disabling a plugin does not hide its home page results

### Checks

- [x] I have checked that this issue has not already been reported.

- [x] I am using the latest version of Flow Launcher.

- [x] I am using the prerelease version of Flow Launcher.

### Problem Description

Whether a plugin's home results show seem unrelated to whether it is enabled or disabled
A disabled plugin should not be able to show home results but it does regardless.
The home page and enabled toggles seem to work completely independently.

### To Reproduce

1. Enable home page results for plugin indicator (and enable the plugin if its not)
2. Make empty query
3. Disable plugin indicator
4. Make empty query again

### Screenshots

_No response_

### Flow Launcher Version

2.1.3

### Windows Build Number

10.0.26200.8894

### Error Log

```shell

Replace this line with the important log contents.

```

Start by reproducing the empty-query sequence described in the issue: enable a plugin's home results, then disable the plugin and query again. Trace the home-page result filtering and plugin enabled state; done means disabled plugins no longer contribute home results while enabled plugins still do.
