AccountsService keeps balance polling, state coordination and DB persistence and exposes thin delegators with identical signatures, so routers, deps.py, main.py and executor_service are unchanged. accounts_service.py goes from 1887 to 1344 lines. Distribution outputs verified byte-identical against the previous implementation.
