This PR introduces a simple web-based visualization tool for the -out=report output.

The tool allows users to upload a report.txt file and parses it in the browser. It then displays subtitle page information as visual cards, making the report easier to read and understand.

Features:

  • Upload report.txt file
  • Parse report content in-browser
  • Display subtitle pages in visual sections/cards

This is an initial implementation and can be extended later with features like timeline visualization, filtering, or charts.

…) may return NULL if memory allocation fails. Added checks and call to fatal(EXIT_NOT_ENOUGH_MEMORY) to prevent potential NULL dereference.

Added memory allocation check for language string.
This HTML file provides a user interface for visualizing CCExtractor reports, allowing users to upload a report.txt file and display relevant results.
