* Swap: populate 'status' from 'btc/swap' response instead of waiting for first websocket input.
## Issue
Clsoes 5975: swap stop at processing even though response comes through
## Notes
Occasionally, the first websocket message doesn't come through (seems like the commerce didn't send?). There's really no need to wait for one more 'status=NEW' message to ensure the right data is being populated (being over-cautious here).
* Beautify the "exact amount" advice.
* CopyableText: add 'onCopy' for clients to change the text-selection
* Swap: only copy the amount (without currency)
## Issue
5873: Rounds 2 of LBC swaps
## Notes
It was an intended feature to include the currency -- I can paste the full string into my note book, while pasting into wallet apps like Exodus will automatically trim off the currency anyway.
Regardless, removed the 'feature' :D
- For the active swap, switch from polling to websocket. The returned data is now the Charge data from the commerce, so some parsing will be required.
- Allow the user to send other coins that the commerce supports.
- Only save the 'chargeCode' to the wallet. The other data can be repopulated from this.
- Store the receipt currency. I'm not sure if the commerce supports sending bits from various coins. Take the coin that came with the 'COMPLETED' message for now.
- Fix 'lbc' calculation to match IAPI side.
- Allow users to see full detauls from "View Past Swaps".
- String cleanup
- GUI cleanup.
While it would be nice if we can swap anonymously through Desktop, the IAPI will tie a wallet address with an account. Final decision is to require authentication.
- Users should be able to see the entered and promised amount, otherwise they might forget how much to send over.
- This change also prepares for the future upgrade to support multiple coins.
