Fix double delete confirm, inline place name editing, preserve assignments on trip extend

- Replace double browser confirm() with single custom ConfirmDialog for place deletion
- Add inline name editing via double-click in PlaceInspector
- Rewrite generateDays() to preserve existing days/assignments when extending trips
- Use UTC date math to avoid timezone-related day count errors
- Add missing collab.chat.emptyDesc translation (en/de)
