Pull Request Overview

This PR refactors the prompt word configuration system to support multiple optimization configurations and prevent user prompt interference. The changes move from a single custom prompt replacement system to a multi-configuration optimization approach that enhances the original prompt template.

• Restructured UI to use a new PromptOptimizationConfig component for better configuration management
• Modified backend services to support multiple prompt optimization configurations instead of single prompt replacement
• Updated the report generator to apply optimization configurations additively to the base template
