CHIA-4458 Annotate debug_spend_bundle.py (#21530)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Low Risk**
> Annotation-only changes to a debug utility with no runtime behavior
impact.
> 
> **Overview**
> Adds **mypy type annotations** to
`chia/wallet/util/debug_spend_bundle.py` so the wallet spend-bundle
debug helper is fully typed: `disassemble` now returns `str`, and
`debug_spend_bundle` takes a `SpendBundle` and `bytes32` agg-sig
additional data.
> 
> **Removes** `chia.wallet.util.debug_spend_bundle` from
`mypy-exclusions.txt`, so mypy will type-check this module instead of
skipping it (CHIA-4458).
