v4.7.40 — Fix: Logo Watermark No Longer Tiles

Fixed the Institute Logo print watermark (added in 4.7.39) still tiling/repeating across the marks table instead of appearing once, auto-fit and centered as intended. The print stylesheet applied the same repeating background rule to both watermark sources regardless of which was selected. Now branches per source: Institute Logo displays no-repeat, centered, scaled to fit; Text keeps its original tiled/repeating display, unchanged.
