fix(streamlit): Add Re-upload and Gitea Sync buttons to Apps table

Restores missing functionality in the Streamlit dashboard:
- Re-upload button: Upload new .py/.zip to replace existing app code
- Gitea Sync button: Pull latest changes from Gitea repository

The buttons appear in the Apps Library table for each app.
