feat: Leads-Aktionsbuttons icon-only + WOID des Akquise-Tickets

- Maps/Website/Repo nur noch Icon (title/aria-label bleiben)
- WOID je Lead als klickbarer Chip -> /tickets?woid= (Lead->Kunde->Akquise-Ticket, live in useLeads gejoint)
- useWorkorders: woid server-seitig filterbar (macht den bisher wirkungslosen WOID-Filter nutzbar)
- TicketsPage: ?woid= Deep-Link liest Param, filtert ueber alle Status
