Exercise GIFs Implementation

Summary

Add support for exercise GIFs in the MuscleLib API, enabling animated exercise demonstrations in the frontend without storing binary files in the database.

Goals

• Provide animated GIF demonstrations for exercises
• Keep the database free of binary media files
• Standardize how GIFs are accessed by the frontend

Tasks

• Define the folder structure for storing GIF files
• Update the exercise schema to include GIF paths
• Adjust API routes to return GIF paths
• Ensure consistency with the existing image handling pattern
• Test GIF consumption in the frontend

Constraints

• GIF files must not be stored in database
• Only file paths or URLs should be persisted
• File structure must be predictable and standardized
• The API should only expose paths, with no media processing
