feat: switch from angular/AJAX+Boostrap to HTMX+PicoCSS

I spent 3 hours updating Angular 10 to 11 yesterday and the migration is not fully complete. Mind you, the current version of Angular is 19 and the recommendation is to upgrade only one major version at a time.

Now I spent just 2 hours to write a complete delegated dialog implementation using HTMX instead of making AJAX requests and using Angular to dynamically render results.

Instead, HTMX is a hypermedia framework that is declaratively configured to make HTTP requests and place responses into the HTML DOM. OSLC, being an LDP REST API built with hypermedia principles at heart is perfectly aligned with HTMX. A lot of code can be removed as a result.

One of the best things is that HTMX does not intend to make breaking change like modern frontend frameworks and be more like jQuery in terms of stability. I think it's a perfect fit for the refimpl that needs to reduce the maintenance burden.

this tiny bit of HTML is what gets rendered every time HTMX makes a search request and it dynamically replaces the contents of the #search-results div with this content returned by the server. Simple and easy.
