TDIP_EE-86: Fix deprecated DSL args

Overview

This PR addresses deprecated argument usage in the DSL component of the project.

Changes

• Updated the build_range method in lib/class-dsl.php to use modern argument keys:
  • Replaced 'from' with 'gte' (greater than or equal to)
  • Replaced 'to' with 'lte' (less than or equal to)
• The value format (date strings in 'Y-m-d H:i:s') remains unchanged.
• These changes align the output with current conventions and improve compatibility.

Impact

• Ensures the codebase no longer uses deprecated keys for range queries.
• Improves maintainability and future-proofs the DSL API.

Testing

• Please verify that range queries still function as expected and return correct results with the updated keys.
