Added a re-usable "yes/no" confirmation modal where the client just sets the question string and gets a callback "OK" or "Cancel" is clicked.
It doesn't make sense to create one modal for each confirmation, especially when the modal is only used in one place.
Replaced one of the existing modal as an example.
* 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.
