Zammad sync performance + liitteiden näyttö tikettilistassa

- Rajoita artikkelien haku max 10 tikettiin per sync (loput on-demand)
- Curl timeout 15s + connect timeout 5s
- Frontend: IMAP ja Zammad haetaan rinnakkain (Promise.allSettled)
- Auto-refresh: Zammad sync ei blokkaa tikettien latausta
- Hakaneula-ikoni (📎) tikettilistassa kun viestissä on liitteitä
- has_attachments, source, zammad_group, ticket_number tikettilistaan
