refactor: remove most unnecessary redux hooks

fix: optimise throttle and hooks ...

In the process of fixing some hook dependencies, I introduced a bug
which caused the application to rapidly send requests to the Krist
server (luckily I was using a local Krist instance). To raise awareness
of this if it happens again in the future, I added a notification that
appears whenever the rate limit is hit. Ideally, it should never appear
in production.

chore: update file headers

fix: sync node in redux

feat: sync balances with websocket

feat: show existing wallet categories

feat: mostly finish wallet dialogs
