fix(l10n): low-severity language findings from the usertest panel

- 'Mit Endpunkt verbinden' — no Endpoint/Endpunkt mix
- audit-chain lead term is 'Hash-Kette' everywhere (doctor pill);
  chain detail says 'Verkettung lückenlos geprüft' instead of the
  raw field name prev_event_sha256
- welcome checklist line says who refreshes what
- setup privacy note explains the local model instead of ending in
  a bare model tag
- default project renders localized ('Allgemein') in the switcher;
  sealed-area status pills explain run state on hover
