Improve IBC transfer page for minifront by using the Skip Widget

[hdevalence]

Is your feature request related to a problem? Please describe.

The IBC transfer page in Minifront is currently badly designed. While a complete V2 redesign is coming, we should make it incrementally better in the meantime.

Describe the solution you'd like

• Get rid of the two column layout, replacing it with a regular pane with three tabs:
  • Deposit (Skip)
  • Deposit (Manual)
  • Withdraw
• In the "Deposit (Skip)" tab, use the Skip widget with a default route and filter that routes assets into Penumbra. Example code: Simplify web guide guide#42
• In the "Deposit (Manual)" tab, put the current left pane
• In the "Withdraw" tab, put the current right pane

Describe alternatives you've considered

I'd rather not wait for the V2 UI to be completed, it feels like we could ship something now that would be better without a lot of work in advance of that.
