Make register entries and note popups addressable via url and index
When clicking notes (bubbles) in the edition text or when opening register entries from any context (search, index, edition text) then the url should be updated with a reference to the dialog content so that the dialog can be reproduced when the url is opened in a new browser tab.
Notes don't have any kind of id, we'll use the note's index within the edition page to address it. We will also show that index number in the dialog titles, e.g. "Wissenschaftliche Anmerkung 4".
