refactor: Replace DI in accounts pkg with Ether

[MikuroXina]

What does this PR do?

My library mini-fn has a module Ether, the dependency injection helper. It uses Symbols to determine what are resolved or not.

At first, I'd replaced manual DI in accounts package with Ether as experiment. It would be nicer than calling their constructor of services directly.
