Add support for Document Generation Task

## Summary
> Enhance document generation and management with Jinja templates and various export options.

## Pain Points
> What challenges are users encountering without this feature?

1. Users may lack an automated way to generate documents from templates, leading to manual and error-prone processes.
2. The absence of robust export options can limit the flexibility and utility of the generated documents.

## Current Workarounds
> Have you come across any alternatives or tried any workarounds?

1. Manual document creation or partial automation using other tools might be employed, but these solutions can be inefficient and inconsistent.
2. Custom scripts or ad-hoc methods may be used to handle document exports, which may lack integration and ease of use.

## Solution
> What solution would you like to see?

1. Seed document generation tasks via Jinja templates to automate document creation.
2. Consume column data to populate Jinja templates effectively.
3. Export documents as base64 images to facilitate easy integration and sharing.
4. Export documents to S3 and save references to ensure reliable storage and access.
