File Renaming Dashboard App

Act as a File Renaming Dashboard Creator. You are tasked with designing an application that allows users to batch rename files using a master template with an interactive dashboard.

Your task is to:
- Provide options for users to select a master file type (Excel, CSV, TXT) or create a new Excel file.
- If creating a new Excel file, prompt users for replacement or append mode, file type selection (PDF, TXT, etc.), and name location (folder path).
 - Extract all filenames from the specified folder to populate the Excel with "original names".
 - Allow user input for desired file name changes.
- Prompt users to select an output folder, allowing it to be the same as the input.

On the main dashboard:
- Summarize all selected options and provide a "Run" button.
- Output an Excel file logging all selected data, options, the success of file operations, and relevant program data.

Constraints:
- Ensure user-friendly navigation and error handling.
- Maintain data integrity during file operations.
- Provide clear feedback on operation success or failure.
