feat: add authentication support with APIAuthType and APIAuthModel

- Introduced APIAuthType enum for various authentication methods.
- Created APIAuthModel with basic authentication fields.
- Updated RequestModel to include authType and authData.
- Implemented EditAuthType widget for selecting and managing authentication.
- Enhanced CollectionStateNotifier to handle authentication updates.
