Shoehorn channel-opening flow into first-trade flow

[luckysori]

Fixes #1793.

channel-opening-flow-v0.mp4

TODOs:

• Let user trade normally after channel-opening trade.
• Fix failing UI test. Adapted it with the new flow.
• Add another UI test for when the channel is already established.
• Fix confirmation slider bug when confirming channel configuration.
• Close all bottom sheets when first trade succeeds.
• Add e2e test for submit_channel_opening_order API.
• Use TradeValues to calculate coordinator margin.
• Set channel-opening fee to 0. When we are ready to charge for opening channels we can read this information from the liquidity options through the backend.
• Do not assume coordinator's proportional liquidity in UI and use leverage in TradeConstraints instead.
• Cap coordinator's maximum liquidity per channel.
• Fix webapp if affected.
• Pop all bottom sheets once the channel-opening trade is confirmed.
• Include funding transaction fees, and fee reserve, in channel configuration screen.

@luckysori Quick question without having looked at the PR yet. Will this change have an impact on the webapp?

Great question. My intention was to not change the webapp at the moment, but I didn't do it properly. See: https://github.com/get10101/10101/pull/1974/files#diff-8923b602c94d37f595a2e3736668c11f089c092ba9f4774d4b2ce305619c0b35R221.

I set the optional ChannelOpeningParams to None, but that will always imply that the channel is already open. I will play around with it tomorrow to make sure that it works like it did before this PR. It shouldn't be much work.

I think I fixed it now, but I can't test it because I get an SSL error when running the webapp locally.

@bonomat @luckysori please have a look at #1974 (comment) and let me know what you think. I took it a bit far (which I probably shouldn't have 🙈), but I got too far to stop now 😅 .

I think it looks good, although I would make sure the e2e tests pass before merging.

I can't seem to find the diff between my version and yours, which is a bit unfortunate.

run the e2e tests locally! everything passed. going ahead with the merge.
