Optimize fill_form by removing redundant database calls

[Lochit-Vinay]

Problem

The fill_form endpoint currently calls get_template() twice:

• Once to check if the template exists
• Once again to fetch the template

This results in redundant database queries.

Proposed Solution

• Call get_template() once
• Store the result in a variable
• Reuse it for both validation and processing

Benefits

• Reduces unnecessary database calls
• Improves performance
• Enhances code readability

I can work on this and submit a PR.
