fix(repair): quote ChromaBackend annotation for Python 3.9 compatibility

Browse Source 
`backend: ChromaBackend | None = None` evaluates the X | None union
eagerly at function-definition time, which Python 3.9 rejects with
TypeError: unsupported operand type(s) for |: 'ABCMeta' and 'NoneType'
since the new union syntax is 3.10+. Quoting matches the existing
forward-reference style in repair.py (sqlite_drawer_count, etc.) and
defers evaluation, restoring 3.9 compatibility.
