Title: Remove PHP dependencies and refactor UI rendering to pure HTML templates

Key features implemented:
- Refactored dashboard plugin to remove PHP dependency and implement pure HTML/CSS/JS template rendering
- Updated log-terminal plugin to replace PHP-based UI with native Python HTML template generation
- Modified package manager plugin to eliminate PHP view files and use direct HTML string construction
- Removed all PHP view template files across dashboard, log-terminal, and package manager plugins
- Updated .gitignore to include additional build artifacts and environment files
- Enhanced dashboard with real-time metrics, system information, and network statistics without external PHP processing

The overall change migrates the system from requiring PHP for UI rendering to using pure Python-based HTML template generation, simplifying deployment and removing external dependencies.
