Rebranding zu NextJobs (nextjobs.cc)

- Markenname 'Bewerbungs-Tracker' -> 'NextJobs' im gesamten UI,
  Footer (incl. nextjobs.cc Copyright), Login, Wortmarke in der
  Top-Navi (Next + Jobs-Gradient), Favicon, Swagger/OpenAPI-Titel,
  CalDAV-PRODID, Browser-Erweiterung (manifest, content, background),
  Runner-Log und Doku.
- Funktionale Begriffe (Bewerbungsunterlagen, -datum etc.) bleiben.
- Docker-Registry (git.hackner.dev) als Infrastruktur unberuehrt.
