Script Generation Issues: Instructions Not Saved, Script Not Persisting, Auto-playing TTS

✅ RESOLVED - All script generation issues have been fixed and deployed

Issues Fixed:

1. ✅ 404 "Project not found" Error

• Added dual lookup support (UUID + shortName) to both script generation and retrieval APIs
• Backend now supports both /projects/{uuid}/generate-script and /projects/{shortName}/generate-script

1. ✅ Custom Instructions Persistence

• Custom instructions now save to project data when generating scripts
• Instructions persist across browser sessions and page refreshes
• Added customInstructions field to project schema

1. ✅ Generated Script Persistence

• Scripts now properly save and display after page refresh
• Fixed script retrieval API to work with both UUID and shortName

1. ✅ TTS Auto-Play Prevention

• Removed automatic audio generation on component load
• Audio now only generates when user manually clicks "Generate Audio" button

1. ✅ Manual Audio Caching

• Implemented proper cache-first logic in TTS generation
• Prevents duplicate API calls and unnecessary costs

Verification:

• ✅ Script generation API working with shortName: top-5-national-parks-in-california
• ✅ Script retrieval API working with shortName
• ✅ Custom instructions successfully saved and persisted
• ✅ TTS auto-play disabled, manual generation working

All changes deployed and live. Original 404 error resolved, UX improvements implemented.
