### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current behaviour

It's a bitcoinfaucet.uo1.net testnet node that is sending bitcoins and checking balance. It stopped working and was restarted. I've lost all bug details, but it happens. Restarting node helped.

### Expected behaviour

It should work

### Steps to reproduce

IDK

Looks good, nothing to add. Happy to reACK if you end up taking ryanofsky's suggestions.

I agree that all required headers must be included explicitly without relying on indirect inclusions via other headers.

It is unsigned in Bitcoin Core, so the tests should match it:

https://github.com/bitcoin/bitcoin/blob/5b8990a1f3c49b0b02b7383c69e95320acbda13e/src/kernel/coinstats.cpp#L54


Large positive values for the block height are impossible to hit in tests, but it still seems fine to fix this.

The bug was introduced when the code was written in 6ccc8fc067bf516cda7bc5d7d721945be5ac2003.

This can be tested by passing a transaction with a large locktime and then observing the error:

```
struct.error: 'i' format requires -2147483648 <= number <= 2147483647
```

I'm just looking around, I'm not a Bitcoin core expert.
My understanding is that this is unsigned little endian is `<I`, wouldn't it make sense to change as little as possible here:
```suggestion
data += struct.pack("<I", height * 2 + coinbase)
```
or if we want to mimic the C++ code:
```suggestion
data = struct.pack('<I', (height << 1) + coinbase)
```

(https://github.com/bitcoin/bitcoin/pull/29400#discussion_r1481315962)
Could we keep the format?
```suggestion
struct.pack("<I", txTo.nLockTime)
```

In the instructions you've mentioned it's reproducible - can you add a test that fails before this change, but passes after?

if possible, can you cover it with a test that reproduces the error before this fix - and passes after it?

> wouldn't it make sense to change as little as possible here:

No. `struct.pack` is brittle and confusing. Just look at all the bugs: https://github.com/bitcoin/bitcoin/pull/29400, https://github.com/bitcoin/bitcoin/pull/29399, https://github.com/bitcoin/bitcoin/pull/29363, fa3886b7c69cbbe564478f30bb2c35e9e6b1cffa, ...

Thus, `struct.pack` should be removed from all tests to avoid more bugs in the future.

(https://github.com/bitcoin/bitcoin/pull/29401)
`struct.pack` has many issues:

* The format string consists of characters that may be confusing and may need to be looked up in the documentation, as opposed to using easy to understand self-documenting code.

This lead to many test bugs, which weren't hit, which is fine, but still confusing.

Fix all issues by using the built-in `int` helpers `to_bytes` via a scripted diff.

Review notes:

* For `struct.pack` and `int.to_bytes` the error behavior is the same, although the error messa
