Expose on-chain transactions in events #446
Description
In bitcoindevkit/bdk#432 we exposed on-chain transactions in the payment store.
We should also do this in events, although for the latter I'd prefer to wait until we can filter out channel-related transactions properly to avoid redudant events, e.g., on channel closure.
We also might want to wait until BDK finally includes on-chain events, which might allow us to make the logic a bit more lightweight.

Hi,
This feature is crucial for us at Synonym.
We are building a mobile wallet (Bitkit) on top of ldk-node and need reliable on-chain receive events for core user flows:
• Sending proper payment received notifications (today we can only do this for LN payments).
• Updating balance and transaction history in real time.
• Ensuring UX consistency between on-chain and Lightning inside a single app.
Right now, the lack of on-chain events makes it very hard to offer a smooth combined on-chain + Lightning experience. Even a minimal version of this functionality would already unblock critical product features.
We fully understand the need to filter out channel-related transactions later for noise reduction, but from a product perspective, having basic on-chain events exposed as soon as possible would be a big step forward.
Thanks for the great work on both LDK and BDK
