fix: improve server action resilience and error logging

- Moved Supabase client initialization inside try-catch in Server Actions
- Added safety checks for null Supabase client in magicScan
- Added detailed server-side logging for debugging deployment issues
- Ensures all failure paths return a structured error response instead of 500
