performance for the main screen load

[Jeroen Willemsen]

Improve the performance for the main screen loading by:

• pre-compiling the content for the table as much as possible
• Have a minification step for all the js/css offered (see https://pagespeed.web.dev/analysis/https-wrongsecrets-herokuapp-com/xltdvc76x1?form_factor=mobile)
• find a way to strip css for bootstrap that we will never use?
• load all computed integers from cache (max score)
• stop blocking of rendering
• enable virtual threads
