[SUBS] Design "Superfluid-light" Widget alternative flow

[vmichalik]

Problem

• We can't get people to care about Super Tokens in the widget flow if they're learning about them for the first time there
• It's extra friction to explain Superfluid
• USDCx and similar Super Tokens are difficult to recognise
• The need for wrapping is unclear
• We can eliminate need to top up streams with autowrap but not clear how to maintain underlying balance

Solution

• Make more assumptions in the flow (default selection etc) but allow people to edit
• Don't try to separate out wrapping step, just say "Superfluid balance" or similar
• Minimise steps (skip token/network selection and wrap selection step by default)
• Say USDC instead of USDCx
