Hmm, we should probably just default to Onchain if we don't know what it is.

If we broadcast the transaction but restart before the wallet syncs, won't we lose this data?

Yeah, we need to double-check whether we need to persist this. I think most channel-related transactions will be regenerated/rebroadcast after restart, but not sure if that would be the case for splice-related data?

On-chain payment records don't capture what a transaction was for -- a channel open, splice, close, sweep, or a plain send. Record that classification on each on-chain payment, derived from the type LDK reports when broadcasting the transaction, so it survives restarts alongside the payment. The tag keeps only which channels a transaction relates to; amounts and fees stay on the payment. Existing records keep decoding unchanged. Compatible with the on-chain transaction classification proposed in lightningdevkit#791. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Use the receiver node for receive-side on-chain checks. Co-Authored-By: HAL 9000
Avoid tagging ordinary wallet sends and rebroadcasts as LDK sweeps. They should remain on-chain payments with no transaction type. Co-Authored-By: HAL 9000

Should we persist before broadcasting like we do for splices?
Persist the replacement payment and pending index before enqueueing the replacement transaction. This avoids a crash window where the tx could reach the chain source without a durable payment record. Co-Authored-By: HAL 9000
Keep known on-chain transaction types across wallet sync updates. Co-Authored-By: HAL 9000
Record close, claim, anchor-bump, and sweep broadcasts. Wallet sync can then retain the LDK transaction type. Co-Authored-By: HAL 9000

Fixes #447.
In #888 we started exposing
TransactionTypefor funding-related transactions. Here, we continue that work and also classify the remaining transaction types so they are shown in the payment store.
