Add print cover fields and office profile

- Project settings gain siteAddress, workStage, projectLead and projectEditor (project.update-settings schema version 3, migration 0009); versions 2 and 1 stay executable and keep the current cover values. Snapshot schema 6 carries the fields; older versions upgrade with null. - Global office profile (office name/address) next to the document logo: table document_branding_settings, PUT /api/document-branding/office, editable from the print view toolbar. - Cover page reads all fields; empty values show the "[ergänzen]" marker. The Planstände editor column shows the project editor. - Shared logo constants moved to a dependency-free module so the Next.js bundler can import them.

+  `/projects/:projectId/print` in einem neuen Tab.
+- **Als PDF speichern / Drucken** nutzt den Druckdialog des Browsers
+  (Ziel „Als PDF speichern“). Der Dokumenttitel `Leistungsbilanz – <Projekt>`
+  wird als Dateiname vorgeschlagen.
+- **Planformat** schaltet die Verteilerpläne zwischen A4 quer und A3 quer um.

+## Seiten
+
+1. **Deckblatt (A4 hoch)** – tabellarisch: Projekt, Planverfasser, Dokument,
+   Planstände (aus benannten Sicherungspunkten) und Inhalt. Leere Angaben
+   erscheinen als orangefarbenes „[ergänzen]“.
+2. **Verteilerübersicht (quer)** – Versorgungsstruktur und Tabelle je
+   Verteiler mit Stromkreisanzahl, P<sub>inst</sub> (Anzahl × Leistung je
+   Stück), P<sub>Geräte</sub> (mit Geräte-GZF), Verteiler-GZF,
+   P<sub>gl</sub>, I<sub>B</sub> und „Σ inkl. unterlagert“.
+3. **Verteilerpläne (quer, je Verteiler)** – Titelleiste mit
+   Verteilernummer, Bezeichnung, Örtlichkeit, Netzart, „Gespeist von“ und
+   P<sub>gl</sub>; darunter Kopfkomponenten, Gruppen, Stromkreise
+   (mehrzeilige mit Sammelzeile und eingerückten Gerätezeilen),
+   Gruppensummen und Verteilersumme. Fehlende Kabelangaben sind als „offen“
+   markiert. Die Titelleiste steht im Tabellenkopf und wiederholt sich beim
+   Drucken auf Folgeseiten.
+
+Seitenformat, Ränder und „Seite x von y“ kommen beim Drucken aus benannten
+`@page`-Regeln (`lb-portrait`, `lb-landscape`), die die Seite zur Laufzeit
+einfügt. Die Bildschirmansicht zeigt Blätter in Papiergröße; die exakte
+Seitenaufteilung langer Verteilerpläne entsteht erst beim Drucken.
+
+## Vorläufige Punkte
+
+- **Einspeisung / Hierarchie:** `fedFrom` ist Freitext. Die Übersicht ordnet
+  einen Verteiler nur dann unter, wenn der Text genau der Nummer oder
+  Bezeichnung eines anderen Verteilers entspricht; „Σ inkl. unterlagert“ ist
+  eine einfache Summe ohne übergeordneten GZF. Die fachliche Verknüpfung
+  (Verteiler und/oder speisender Stromkreis) und die Summierungslogik sind
+  offen.
+- **I<sub>B</sub>** ist ein symmetrischer Drehstromwert
+  S / (√3 · U<sub>3~</sub>) mit S aus P / cos φ je Gerätezeile
+  (fehlendes cos φ = 1) und Verteiler-GZF.
+- **Corporate Design:** Farben (`--pd-*` in
+  `src/frontend/print/print-document.css`) und Schrift (Arial) sind aus Logo
+  und kbp-Präsentationsmaterial abgeleitet und werden durch die offizielle
+  CD-Vorgabe ersetzt, falls diese abweicht.
+- **Planstände:** Die Spalte „Bearbeitung“ zeigt für jeden Planstand die
+  aktuelle Bearbeitung aus den Projekteinstellungen, weil Sicherungspunkte
+  (noch) keinen Bearbeiter speichern.
