m df321acb63 feat(t-paliad-097): clickable checklist references + Vorhandene Instanzen tab
Two related checklist UX gaps:

1. Checklist events in a project's Verlauf tab were unclickable — and
   nothing in the project_events row carried the originating instance ID.
   Add an `insertProjectEventWithMeta` helper, write
   {"checklist_instance_id": <uuid>} as project_events.metadata for
   checklist_created / _renamed / _linked / _unlinked / _reset (skipped
   for _deleted — instance is gone). Surface metadata on
   /api/projects/{id}/events and on dashboard recent_activity. The
   Verlauf renderer wraps the title in <a href="/checklists/instances/{id}">
   when metadata.checklist_instance_id is present, and the dashboard's
   activity feed deep-links the project ref to the instance directly for
   checklist_* events. Existing rows (metadata `{}`) stay non-clickable —
   no migration backfill needed.

2. /checklists previously demanded a template pick before any existing
   instance was reachable. Add a tab nav (Vorlagen / Vorhandene Instanzen)
   using the existing entity-tab pattern. New endpoint
   GET /api/checklist-instances and ChecklistInstanceService.ListAllVisible
   return every visible instance across templates + projects, joined with
   project ref/title and sorted by created_at DESC. Rows show template,
   instance name (linked), project link (or "Persönlich"), progress bar,
   and created date. URL state (?tab=instances) keeps the active tab
   shareable. EN + DE i18n covered for tab labels and column headers.

Also adds event.title.checklist_* localizations for the Verlauf header
that translateEvent looks up.
