_cleanup_event_files() removes the on-disk artifacts when an event is
hard-deleted (binary, a5_pickle, sidecar, h5). Today's .TXT
preservation feature added a new on-disk file (_ASCII.TXT next to the
binary) but the cleanup didn't know about it — so any event deleted
via /db/events/{id} (single) or /db/events/delete_bulk (or the
Terra-View "SFM Event DB Manager" UI which proxies through to those
endpoints) was leaving orphan .TXT files in the store.
Added "txt" to the cleanup list using the new
WaveformStore.txt_path_for(). Safe for old events without a .TXT —
the exists() check skips the unlink.
