fix(bounds): respect disablePadding and explicit position props in bounds calculation

Bounds calculation now honours the disablePadding flag (locks content
when it fits the wrapper) and applies minPositionX/maxPositionX/
minPositionY/maxPositionY prop overrides. Pinch and wheel handlers
enforce these explicit bounds via hasExplicitPositionBounds. Initial
state creation clamps scale to minScale/maxScale and respects position
bounds.

Also includes:
- src/ added to published package files for source maps
- ResizeObserver mock in jest.setup for centerOnInit flows
- Test assertions updated for synchronous setTransform calls and
  correct pan directions
- Storybook enhanced with bounds overlay, cinema venue example, and
  mixed-content demos
