[feature]: Expand the notification scope of SubscribeRfqEventNtfns

[lukegao209]

Conditions:

1.	A Taproot Asset Channel exists between Alice and Bob.
2.	Alice adds a Taproot Assets Invoice using the AddInvoice method.
3.	Alice receives a PeerAcceptedBuyQuote event notification, but Bob does not receive any notification.

Requirement:

1. Add Notification for Bob:
   Enhance the notification system so that Bob also receives a notification when Alice creates a Taproot Assets Invoice. This will allow Bob’s tapd to accurately identify key invoice details, such as asset_amount and AssetRate. Providing Bob with this information will help tapd process its own business logic more effectively.

2. Include baseScid Field:
   Add a baseScid field to the notification data. This field will facilitate the identification of the specific channel and associated assetId, improving clarity and processing accuracy for both Alice and Bob’s tapd.
