ShroominicandClaude Opus 4.8 477acedb05 fix(refund): durable, balance-versioned refund idempotency (closes #412) ...

DB-persisted, balance-versioned refund idempotency replacing the in-process
refund-token cache. Every credit (cashu topup, Lightning topup, new-key) bumps
ApiKey.balance_version atomically; /refund re-serves a stored token only at the
current version and only if unredeemed. Covers the Lightning-topup path and
multi-worker, which the in-process cache missed.
