fix(rwallet): chain filter now updates all displayed data + chain proportion bar

- Stats, balance table, and DeFi positions all filter by selected chain
- Added proportional color bar showing each chain's share of total value
- Chain buttons show USD value + percentage on hover
- Bumped JS cache version to v=21
