refactor(commit_generator): Improve code readability and styling

Minor code cleanup to enhance readability and adhere to styling conventions.

*   **Enhancements & Refinements**:
    *   Wrapped long lines for better readability in logger configuration, console theme definition, commit message panel printing, and dry run output.
    *   Removed an unnecessary f-string from the commit generation status message.
