Ingestion module for foundational DP

[Aashutosh-cognite]

depends on PR #275

This module owns the ingestion workflow, transformation definitions, auth groups, and data model configuration tooling for the Foundation Deployment Pack. It lives under modules/common/ and is registered in packages.toml as part of dp:foundation.

What's included

Two-phase workflow driven entirely by config flags — no YAML editing required when toggling a source on or off:

• Phase 1 (Population) — transformation tasks for PI, OPC-UA, and SAP run in parallel, landing data into the active DM views (ISATimeSeries, ISAAsset, Equipment, WorkOrder, Operation for ISA; FunctionalLocation, TimeSeriesData, Files for CFIHOS).
• Phase 2 (Contextualization) — relationship transforms run after population completes, setting Equipment.asset and Operation.workOrder properties.

Which phases and tasks are included is controlled by enabledSources, enabledContextualization, and dataModelVariant in default.config.yaml.

Key files

• scripts/build_workflow.py — generates wf_ingestion_v1.WorkflowVersion.yaml from per-task snippets based on the active config. Run with --check in CI to detect drift.
• scripts/configure_datamodel.py — writes DM-variant variable overrides (schemaSpace, view names, instanceSpace) into all discovered config.<env>.yaml files, covering both contextualization modules (cdf_entity_matching, cdf_file_annotation) and source system modules (cdf_pi_foundation, cdf_sap_foundation, cdf_opcua_foundation, cdf_files_foundation).

Code Review

This pull request introduces the cdf_ingestion_foundation module, which provides a framework for orchestrating two-phase ingestion workflows (population and contextualization) across PI, OPC-UA, and SAP source systems. It includes a Python generator script to build workflow versions from task snippets, various SQL transformations, and authorization group definitions. Review feedback primarily addresses Python style guide violations in the build script—such as import sorting, the need for typed data structures (dataclasses/Pydantic), and proper logging—as well as security recommendations to restrict overly broad wildcard scopes in the authorization group capabilities.

Should we remove the Transformation examples here - maybe just use this module to set up the generic auth groups?
