fix(korrespondenz): address 10 visual and functional regressions

- Strip full-bleed: remove max-w container, put strips at page level
- Remove page heading/subtitle above strip (not in spec)
- Swap button always visible (drop opacity-0, keep pointer-events-none)
- Korrespondent placeholder "Alle Korrespondenten" + label "— optional"
- Add placeholder prop to PersonTypeahead; add onfocused callback prop
- "Person suchen" button now focuses #senderId-search instead of no-op navigate
- Wire CorrespondentSuggestionsDropdown on correspondent field focus
- Hint bar: bold name via <strong>, year-only dates (no ISO strings)
- Asymmetry bar: use first name only to prevent label overflow
