Local js/css scripts

[marcogruhl]

From Discussion: #113
I hit a small road block when using PiOSK in an air gaped environment. The js and css scripts (bootstrap.bundle.min.js, bootstrap.min.css, jquery-3.7.1.min.js) don't load. I also can imagine usecases where the Pi are not allowed to load something from outside.

I implemented the downloading of the external scripts within the setup script and the paths in the index.html from the external to local.

Pull Request Overview

This PR enables PiOSK to function in air-gapped environments by downloading external JavaScript and CSS dependencies locally during setup instead of relying on CDN links. This addresses the issue where external scripts (Bootstrap and jQuery) fail to load when internet access is restricted or unavailable.

• Downloads external dependencies (jQuery, Bootstrap JS/CSS) to local files during setup
• Updates HTML to reference local files instead of CDN URLs
• Maintains integrity hashes for security validation

The integrity hashes will fail when loading local files since they were calculated for the original CDN versions. Remove the integrity attributes or update them to match the downloaded files' hashes.
