feat: Bericht erstellen shows full PDF preview before download

Dialog now opens at md size (88vh), shows a progress bar while
generating, then reveals the full report document: header, all 4
signal sections with colour-coded separators, confidence scores,
sources, dates. Document is blurred during generation and sharpens
when ready. Herunterladen button stays disabled until preview is ready.
