fix: S3 auto sync ENOENT error with custom-minapps.json

- Add file existence check in FileStorage.readFile to prevent ENOENT errors
- Improve error handling in custom-minapps.json loading across all components
- Add robust JSON parsing and validation for custom minapps
- Handle concurrent access during S3 auto sync operations

Fixes #11255
