feat(neon_framework): Implement remote wipe

[provokateurin]

Closes #43.
Not all data is deleted yet, but that will be fixed in #2114.

Tests for the changes in AccountsBloc still have to be written, but there are no tests for it at all so far, so it is a slightly bigger task than I anticipated.

Note that this implementation is not per docs, as we only check if the account needs to be wiped once per app start and not for every 401/403 response we receive.
This should still be decently safe and definitely more safe than not implementing it at all.
