fix: Add retry mechanism and timing delays for React state sync

- Wait 1 second after layout load for React to process
- Retry listObjects up to 3 times to ensure state is available
- Add 0.5s delays after adding new text objects
- Keep 2s wait before final export

Fixes timing issues where text updates weren't reflected in export.
