v1.46.3: re-check of v1.46.2 — HP-1462-01

The startup sweep resolved its runtime data with get_data(hass), which lists
only LOADED entries — during async_setup_entry the entry is still
SETUP_IN_PROGRESS, so it always got None and degraded to removing streaming
temporaries. The real collection was then 24 hours away, and an instance that
restarts more often than that never ran it at all. It closes over the
object created a few lines above instead; the callback is unregistered with the
entry, so that matches the lifecycle.

The test that was meant to prove the previous fix passed for the wrong reason:
it seeded the strays BEFORE config/set, which collects too, so nothing was left
for the restart to find. Now seeded after the save, plus two more — one firing
the interval callback on its own, and one running a reload and a save
concurrently to assert the accepted config never references a file the sweep
removed (they share the write lock; this pins that they must).
