- Remove Aktualisieren button from Leadspeicher
- Bulk actions: remove status dropdown
- Export: LeadVault Excel-only, clean columns, freeze row + autofilter
- Export dropdown: click-based (fix overflow-hidden clipping)
- ExportButtons: remove CSV, Excel only everywhere
- Maps page: post-search Anymailfinder enrichment button
- ProgressCard: "Suche läuft..." instead of "Warte auf Anymailfinder-Server..."
- Quick SERP renamed to "Schnell neue Suche"
- Results page: Excel export, always-enabled download button
- Anymailfinder: fix bulk field names, array-of-arrays format
- Apify: fix countryCode lowercase
