Extend automatic form generation endpoint with sanity checks

[danilomeireles]

What changes did you make?

Added three new validation checks to the generateNewTemplate function to ensure data integrity and prevent mismatched form generation:

Template ID validation: Verify that the requested template_id matches the template stored in ICM metadata
Tool validation: Ensure the ICM metadata indicates "formfoundry" as the designated tool (case-insensitive)
Area validation: Validate that the request area parameter matches the ICM category when an area is specified (case-insensitive, optional)

Why did you make these changes?

These validations prevent potential issues:

• Ensures forms are only generated for the correct template ID, preventing cross-template data corruption
• Confirms that the attachment is designated for FormFoundry processing, preventing form generation by other tools
• Validates that form requests are processed in the correct business area/category context
• Provides clear feedback to clients when requests contain invalid or mismatched data

What alternatives did you consider?

No other alternatives were considered as this endpoint is the right place for these validations.
