core/state: handle *bintrie.BinaryTrie in mustCopyTrie (#34758) 
## Problem

`mustCopyTrie` in `core/state/database.go` panics on any trie type not
in its type switch:

```go
func mustCopyTrie(t Trie) Trie {
    switch t := t.(type) {
    case *trie.StateTrie:
        return t.Copy()
    case *transitiontrie.TransitionTrie:
        return t.Copy()
    default:
        panic(fmt.Errorf("unknown trie type %T", t))
    }
}
```

On UBT-backed databases (`state.NewUBTDatabase(...)`, used by
`blockchain.go:2124` when the triedb is configured for binary trie),
`StateDB.trie` is `*bintrie.BinaryTrie` — so every `StateDB.Copy()` call
(hit from `statedb.go:699` and the `*trie.StateTrie` branch of
`state_object.go:546`) crashes with `unknown trie type
*bintrie.BinaryTrie`.

## Fix

Add the `*bintrie.BinaryTrie` case. `BinaryTrie.Copy()` already exists
at `trie/bintrie/trie.go:372` and produces a correct deep copy — this
just wires it into the switch.
