Pull Request Overview

This PR implements a new app-specific seed update API that provides a simplified version of the existing seed update functionality. The main difference is that file deletion and link modification capabilities have been removed to suit mobile app requirements.

Key Changes:

• Implemented updateSeedForApp service method that excludes file and link modifications
• Created new PATCH endpoint /app/{seedId} for mobile app seed updates
