Integrate AGLint into the User rules editor

### Issue Details

I suggest integrating [AGLint](https://github.com/AdguardTeam/AGLint) into the User rules editor. Since the User rules editor is often used during filter maintenance, it can also be considered a lightweight version of the [VSCode extension](https://github.com/AdguardTeam/VscodeAdblockSyntax).

### Proposed solution

The recommended functional requirements are:
- If the linter finds any problems, the problematic part must be underlined in yellow / red (yellow for warnings, and red for errors). The error message must be displayed when hovering over the problematic part.
- The linter configuration must be persistent and editable. For this, I recommend a button at the bottom of the editor, which opens a new window where the linter configuration can be edited in JSON / YAML format. Saving invalid configuration must be prohibited.
- The linter should be made optional. For this, I recommend a simple toggle button on the User rules page, which can be used to turn the linter on/off with one click.
- We should consider a quick fix that adds the disable control comment to a rule with one click. This can be useful if the linter reports false positives.
