Reader: Notizen auf Mobile schnell setzbar statt über Randspalte (SW v32)

Auf schmalen Screens saß der Marker-Modus-Button bisher nur in der 150px-
Randspalte — man musste sie erst öffnen (und damit den ohnehin knappen
Lesebereich verkleinern), um überhaupt markieren zu können. Jetzt zusätzlich
ein Marker-Button direkt im Haupt-Header (nur <=600px sichtbar, Desktop
bleibt bei der bisherigen Anordnung in der Notes-Leiste).

Im Marker-Modus legt ein einfacher Tap auf reinen Lesetext (ohne Auswahl)
jetzt direkt eine freie Notiz an der Wortposition an — man muss nicht mehr
den exakten Klick-Punkt in der Randspalte treffen. Das Bearbeiten der
Notiz läuft auf schmalen Viewports über ein neues Bottom-Sheet (volle
Breite) statt über das Inline-Textfeld in der 150px-Spalte, das auf dem
Handy-Keyboard unangenehm zu bedienen ist.

Notiz-Objekte werden jetzt erst bei tatsächlich eingegebenem Text angelegt
und gespeichert (vorher: sofort beim Setzen des Ankers) — verhindert, dass
ein abgebrochener/leerer Tap eine Ghost-Notiz in currentHighlights
hinterlässt. Gilt für alle Eingabewege (Bottom-Sheet UND die bestehende
Inline-Randspalten-Bearbeitung), per Playwright verifiziert inkl. Escape-
Cancel auf Desktop.

Priorität laut Nutzer: Notizen-Erfassung muss auf Mobile gut funktionieren;
dass bestehende Notizen dort weniger prominent sichtbar sind, ist explizit
in Ordnung — die vertiefte Auseinandersetzung mit Notizen bleibt eine
Desktop-Aufgabe.

Verifiziert per Playwright (390×844 mobil + 1280×900 Desktop-Regression):
Marker-Button-Sichtbarkeit, Bottom-Sheet-Flow (Erstellen/Abbrechen/Speichern,
kein Ghost-Eintrag), reale Text-Selektion + Highlight+Notiz weiterhin
funktionsfähig auf Mobile, Desktop-Workflow (Randspalte, Inline-Editor,
Escape-Cancel, Blur-Commit) unverändert.
