Each keeps its name and serves the moved names through a module __getattr__
(PEP 562) rather than a top-level re-export: every child imports back from
its parent, so a plain import would be circular. The lookup goes through
importlib.import_module, which is a call rather than an import statement,
so it needs no linter suppression. Return type is a _Reexport alias -- mypy
rejects `object` as not callable at the call sites, ruff rejects a bare Any.
Also fixes two leaks where tests wrote to the user's real config, both
caused by a redirected constant moving to a new module while conftest kept
patching the old one:
- APPROVED_EXCEPTIONS_FILE / EXCEPTION_AUDIT_LOG moved to _whitelist_locking;
the suite had appended 27 fixture entries to the live exception_audit.log.
- _OWNED_IDS_CACHE_FILE was never redirected at all: it is derived from
CONFIG_DIR at import time, so it captured the real path before the fixture
could patch it, and the suite overwrote the user's owned-games cache.
Both are now verified by md5summing ~/.config/steam_backlog_enforcer before
and after a full run, which is the only check that actually catches this --
the tests pass either way.
