pool: daemon crashes if unable to reconcile local order state w/ a replaced pending batch

Nobody has claimed this yet.

Reported by a Lightning Terminal user:
```
[ERR] LITD: Could not start subservers: unable to start account manager: unable to resume account X: unable to subscribe for account updates: checking pending batch failed: error removing pending batch artifacts: error abandoning channels from previous pending batch: error locating channel outpoint: no channel output found in batch tx for matched order Y
```

The start of the failed code path is here: https://github.com/lightninglabs/pool/blob/master/auctioneer/client.go#L579-L587

We go to abandon the channel shims we have have created: https://github.com/lightninglabs/pool/blob/3e49f4c5c83b5451181d7b895831580cd113eda3/funding/manager.go#L999-L1005

Ultimately failing here when it can't find an output its looking for in the batch execution transaction: https://github.com/lightninglabs/pool/blob/3e49f4c5c83b5451181d7b895831580cd113eda3/funding/batch.go#L95-L105

Start in auctioneer/client.go at the account-resume path, then trace the pending-batch cleanup in funding/manager.go and the missing-output handling in funding/batch.go. Reproduce or test the replaced pending-batch state and define done as allowing the daemon to recover without crashing when the expected channel output is absent.
