Pulls in template changes: export_serving.py for atomic DuckDB swap,
supervisor export step, SQLMesh glob macro, server provisioning script,
imprint template, and formatting improvements.
Template scaffold SQL models excluded (padelnomics has real models).
Web app routes/analytics unchanged (padelnomics-specific customizations).
