Make txAdmin a PWA

[Cocodrulo]

This pull request introduces Progressive Web App (PWA) support to the project, enhancing the user experience on mobile devices and enabling features like app installation and theming. The main changes involve adding a web app manifest and updating the HTML metadata to support PWA capabilities.

PWA support and metadata enhancements:

• Added a new manifest.json file to the panel/public directory, specifying app details, icons, colors, and display settings for PWA functionality.
• Updated panel/index.html to link the manifest, set theme colors, and add mobile web app meta tags for improved appearance and installability on mobile devices.
