[BUG]: pgSchema enum names starting with native type prefixes lose schema qualifier in generated SQL

### Report hasn't been filed before.

- [x] I have verified that the bug I'm about to report hasn't been filed before.

### What version of `drizzle-orm` are you using?

0.45.2

### What version of `drizzle-kit` are you using?

0.31.10

### Other packages

_No response_

### Describe the Bug

Reproduction code

```ts
import { pgSchema } from "drizzle-orm/pg-core";
export const mySchema = pgSchema("myschema");
export const charType = mySchema.enum("char_type", ["x", "y"]);
export const items = mySchema.table("items", {
kind: charType("kind").notNull(),
});
```
then run `drizzle-kit generate`, the generated migration is as follows

```sql
CREATE TYPE "myschema"."char_type" AS ENUM('x', 'y');
CREATE TABLE "myschema"."items" (
"kind" char_type NOT NULL -- missing "myschema".
);
```

The problem is that my enum is called `char_type` and the code checks the native types for a prefix, not the full type, so `char_type` matches the native `char` and it doesn't get included.
