Beschreibung

### Which Cloudflare product(s) does this pertain to?

D1

### What version(s) of the tool(s) are you using?

3.51.2 [Wrangler]

### What version of Node are you using?

21.6.10

### What operating system and version are you using?

macOS Sonoma 14.4.1

### Describe the Bug

### Observed behavior
When exporting a D1 database with some relations using `npx wrangler d1 export`, it can generate an SQL file that cannot be imported again (`✘ [ERROR] no such table: main.B`). This is due to INSERTs happening before all tables are created.
I've prepared a minimal reproduction repository: https://github.com/hrueger/d1-export-order

### Expected behavior
All `CREATE TABLE` queries happen first, all `INSERT`s afterwards.

### Steps to reproduce
See https://github.com/hrueger/d1-export-order

in short, you need two tables, where the first table has a foreign key to the second table. Insert one row each, export that and try to import it again using `npx wrangler execute ... --file ...`

In the minimal reproduction there's also a fixed sql file, where the `INSERT` is just moved to the bottom.

### Please provide a link to a minimal reproduction

https://github.com/hrueger/d1-export-order

### Please provide any relevant error logs

```
✘ [ERROR] no such table: main.B
```

As per our discord conversation on friday, I'm tagging @geelen. Thanks for looking into this!

Start with the minimal reproduction repository and run `npx wrangler d1 export`, then try importing the generated file with `npx wrangler execute ... --file ...`. Compare the generated SQL with the fixed SQL file, and verify that exports with foreign-key relations can be imported successfully, with all tables created before rows are inserted.
