feat(geschichten): integrate DocumentFilterChip into list page

Add DocumentFilterChip to the filter bar, extract emptyMessage as $derived.by() with person-wins precedence, and add removeDocument navigation helper. Update tests: add document-filter chip and empty-state-precedence suites, fix person-chip click test to use native element.click() + vi.waitFor() for reliable Svelte 5 onclick triggering.
