GIF Playback Support

Summary

Add support for animated GIF playback within Encamera so that imported GIF files play their animation rather than displaying as static images.

User Report

A user on iPad imported GIF files from their Photos app into Encamera and found that the GIFs do not animate/play. They appear as static images instead.

Current Behavior

GIF files can be imported into Encamera, but they display as still images without animation.

Requested Behavior

GIF files should play their animation when viewed within the Encamera vault, maintaining the same animated playback experience users expect from their original gallery.
