Bobtimus should dictate asset IDs

At the moment bobtimus as well as the wallet have their own asset configurations. Especially in dev mode this leads to problems because each tool needs to be compiled/configured with the same asset ID.

The actual problem is that the wallet assumes to know the asset ID when executing certain actions. E.g.

• for our atomic swaps we have an SSE endpoint which returns bid/ask prices for usdt/btc implying the asset IDs
• in the wallet we have makeSellCreateSwapPayload/makeBuyCreateSwapPayload and makeLoanRequestPayload. Each imply to know about the asset IDs.

Imho a better architecture would be to let bobtimus dictate the asset IDs. When forwarded to the wallet the wallet can then reason about these IDs. In fact, it should use the pre-configured asset IDs for displaying purposes. For example, if the user clicks on swap in Waves, the wallet pops up and the user needs to confirm. Here the wallet should either display the asset ticker (LBTC/LUSDT) for known asset IDs or the asset ID itself.

In production, the wallet can retrieve asset tickers from blockstream's registry and in devmode we could either pre-configure it or provide an additional endpoint to bobtimus.
