Feature: Image manipulation — crop, resize, watermark

[jongalloway]

Add tools for image manipulation within slides.

Suggested:

• pptx_get_image_properties (read dimensions, DPI, format from slide context)
• pptx_crop_image (adjust image crop bounds)
• pptx_resize_image (change image dimensions while maintaining aspect ratio)
• pptx_add_watermark (overlay watermark on slide/presentation)

Business value: brand compliance, image formatting, presentation security.

Complexity: Medium-High.
