feature: Collapsed Account list and expanded token balances

[Arrowana]

The account list is quite low level as it does not tell you anything about type or which ix even uses it. In general i found myself looking at token change and ixs below

Collapse the account list.

The only loss is not seeing the lamports change + post balance, maybe this can also be added to the top card? Minor compression in the overview card would allow compressing the entire page height further
