list_sessions() silently dropped corrupt session files whose filename
stem was a legacy non-base64 name (e.g. telegram_12345.jsonl from the
old lossy path scheme). The repair path called _repair(fallback_key),
but _repair re-encodes the key via _storage_key(), producing a
different base64 filename that never matches the actual file on disk.
Add an optional path parameter to _repair so callers can pass the
actual file path directly, bypassing the key-to-filename round trip.
