Pedantic eslint complaints

Got some messages from eslint. Maybe you can adjust for the empty objects we love in Rust.

Code:

```ts
export type ExecuteMsg =
| {
bond: {};
}
| ...
```

Error message:

```
19:11 error Don't use `{}` as a type. `{}` actually means "any non-nullish value".
- If you want a type meaning "any object", you probably want `Record` instead.
- If you want a type meaning "any value", you probably want `unknown` instead.
- If you want a type meaning "empty object", you probably want `Record` instead @typescript-eslint/ban-types
```

I just manually updated mine to `Record`

Start by locating the TypeScript code-generation path that emits the ExecuteMsg empty-object variants and run the relevant lint checks. Replace generated empty-object types with the intended empty-object representation, then confirm the generated output no longer triggers @typescript-eslint/ban-types.
