The .entity-table tbody tr CSS rule sets cursor: pointer on every row,
but the three checklist-instance tables only wired navigation to the
name cell's <a>. Clicks on Vorlage / Fortschritt / Angelegt cells looked
clickable yet did nothing.
Added row-level click handlers (skipping inner <a>/button so the
project-link cell and delete button still work) in:
- checklists.ts (Vorhandene Instanzen tab)
- projects-detail.ts (Checklisten tab on project detail)
- checklists-detail.ts (instance list on template detail)
Search-result anchors (handlers/search.go) already worked since they
are real <a> elements, no row handler needed.
