Pull Request Overview

Adds the ability to capture or select images (and other media) in the Duck.ai WebView, handling permissions, moving files into cache, and cleaning them up afterward.

• Integrates a file chooser that supports camera, gallery, and audio capture with proper permission flow
• Introduces dialog strings for capture permission rationale and error messages
• Post-processes captured media by moving it into a cache subdirectory and scheduling its deletion via WorkManager
