refactor: update NewLocalFileService to use unified LocalFileServiceConfig

- Introduce `LocalFileServiceConfig` struct to consolidate `RootDir` and `PublicBase` configurations.
- Simplify `NewLocalFileService` by replacing individual parameters with a single configuration struct.
- Adjust fileserver adapter initialization to align with the updated configuration structure.
