Add payload schema handling for task indexing

This change introduces support for handling payload schemas during task indexing. By incorporating the `payloadSchema` attribute into various components, we ensure that each task's payload structure is clearly defined and can be validated before processing.

- Updated the TaskManifest and task metadata structures to include an optional `payloadSchema` attribute. This addition allows for more robust validation and handling of task payloads.
- Enhanced several core modules to export and utilize the new `getSchemaToJsonSchema` function, providing easier conversion of schema types to JSON schemas.
- Modified the database schema to store the `payloadSchema` attribute, ensuring that the payload schema information is persisted.
- The change helps in maintaining consistency in data handling and improves the integrity of task data across the application.
