Subject: [PATCH] fix: store checkpoints at checkpoint height not 0

Fix checkpoint sync after #292. Before that PR the checkpoint header was stored via `ChainState::store_chain_state` like below making use of `sync_base_height`:

```rust
// First store all headers
// For checkpoint sync, we need to store headers starting from the checkpoint height
self.store_headers_at_height(&state.headers, state.sync_base_height).await?;
```

After that PR its stored at height 0 via:

```rust
storage.store_headers(&[checkpoint_header]).await?;
```

So this PR fixes it by using `store_headers_at_height` again with the actual checkpoint height.
