feat: Projektseite-Toolbar - Icon-Buttons + Textsuche + Kunden-/Mitarbeiter-Filter

- Sync/Neu als Icon-Buttons (Tooltip statt Text), Sync-Icon dreht beim Laden
- Textsuche nach Titel/Subdomain/Repo
- Filter nach Kunde (Dropdown)
- Filter nach Mitarbeiter (ueber zugeordnetes Ticket -> assignedTo)
- alle Filter kombinierbar mit der bestehenden Kategorie-Auswahl
