Subject: [PATCH] refactor: remove unused exported type interfaces

CreateFileParams, UserRow, CreateUserParams, and MultipartFile were
exported but never imported outside their own modules. Narrowed visibility
to module-local to keep the public surface minimal.

Confirmed with knip (zero findings) and all 61 tests passing.
