[bugfix] Use proper atomic units for staking balances

[deangalvin-cb]

What changed? Why?

This updates the internal parsing of balance objects from whole units to atomic units to match other balance usage.

Qualified Impact

This impacts the way balances are parsed internally and should not break any client usage.

toString() might need to change as well, perhaps removes the ETH as it is showing the rawNum, currently

got this when testing locally, but I think it is due to backend returning ETH amount
