Subject: [PATCH 1/2] Add `DecodeWithMemTracking` derive to `CompactProof`
 (#11028)

# Description

Add `DecodeWithMemTracking` derive to `CompactProof` in
`substrate/primitives/trie/src/storage_proof.rs`.

`StorageProof` already derived `DecodeWithMemTracking` but
`CompactProof` in the same file was missed.

## Integration

No integration changes required for downstream projects. `CompactProof`
now implements `DecodeWithMemTracking`, which is a strictly additive
trait implementation. Existing code using `CompactProof` will continue
to work as before.

## Review Notes

Single-line change adding `DecodeWithMemTracking` to the derive macro
list on `CompactProof`:

```diff
-#[derive(Debug, PartialEq, Eq, Clone, Encode, Decode, TypeInfo)]
+#[derive(Debug, PartialEq, Eq, Clone, Encode, Decode, DecodeWithMemTracking, TypeInfo)]
 pub struct CompactProof {
     pub encoded_nodes: Vec<Vec<u8>>,
 }
```

`CompactProof` only contains `Vec<Vec<u8>>`, which already implements
`DecodeWithMemTracking`, so the derive works without any manual
implementation.
