feat(16-01): thread signers and unassignedFieldIds through PdfViewer chain to FieldPlacer

- PdfViewerWrapper accepts and passes signers/unassignedFieldIds to PdfViewer
- PdfViewer accepts and passes both props to FieldPlacer
- FieldPlacer adds signers/unassignedFieldIds to FieldPlacerProps (optional, defaulted to []/ new Set())
- No rendering changes — prop tunnel only for Wave 2 consumers
