Refactor the modals
Currently modals are loaded in the HTML pages and hidden, then managed by fomantic-ui.
We should use HTMX to manage the modals (maybe in conjunction with fomantic-ui). The desirable state would be that
- if javascript is disabled, the modal is actually a new page with the confirm/abort button,
- if javascript is disabled, the behavior stays the same but the modal content is loaded with ajax
