Refactor SMS Provider Classes to Support Nullable API Key and Sender

- Updated KavehNegarProvider and RanginehProvider constructors to accept nullable API key and sender parameters.
- Adjusted methods in both providers to handle cases where the API key or sender may not be set, preventing potential TypeErrors.
- Modified community IDs in graph.json for various entities to reflect updated associations.
- Updated manifest.json with new modification times and AST hashes for KavehNegarProvider and RanginehProvider.
- Added new AST cache files for KavehNegarProvider and RanginehProvider reflecting the latest structure and relationships.
