Fixe SonarQube Reliability-Issues S2789, S3077 und S2184

Browse Source 
S2789 (32 Stellen): null-Checks auf Optional-Feldern entfernt bzw. durch
Objects.requireNonNullElse(field, Optional.empty()) ersetzt. Die zuvor
defensive Behandlung von null-Optionals erfolgt jetzt ueber den
Bibliotheksaufruf, sodass das Verhalten unveraendert bleibt, aber die
direkte Null-Pruefung gegen Optional entfaellt.

S3077 (5 Stellen): volatile-Felder mit Objekt-Referenzen durch
AtomicReference ersetzt (ScheduledExecutorServiceSchedulerAdapter,
BootstrapRunner.guiApplicationRunContext, PdfPreviewPane.currentDocument/
currentRenderer/currentSourceFile, SingleInstanceGuard.socket). Die
PdfPreviewPane-Felder werden auf JavaFX- bzw. Worker-Thread genutzt;
AtomicReference bietet hier konsistente atomare Publikation ohne
Verhaltensaenderung.

S2184 (3 Stellen): Integer-Division SECONDARY_SPACING / 2 durch
SECONDARY_SPACING / 2.0 ersetzt, damit das Insets-Argument als double
ohne implizite Truncierung berechnet wird.
