Refactor parameter merging to async utility function

Replaces direct parameter rule fetching and merging logic with a new async utility function `fetchAndMergeValidCompletionParams` in both configuration and LLM panel components. This centralizes the logic for fetching model parameter rules and merging valid completion parameters, improving code reuse and maintainability.
