Pull request overview

This PR regenerates the management-plane package azure-mgmt-commerce after migrating its source from AutoRest/Swagger to TypeSpec (spec commit a7bdbe74…, API version 2015-06-01-preview, beta release 6.1.0b3). It swaps the legacy msrest-based serialization models for the DPG (_utils/model_base.py) code generation stack, updates the client/config to the {endpoint}-based pattern, and bumps packaging metadata to reflect a beta release requiring Python 3.10+.

Changes:

• Migrated generated code from AutoRest to the Python (TypeSpec/DPG) generator: consolidated per-operation modules into _operations.py, replaced _models_py3.py with _models.py + model_base.py, renamed OfferTermInfoEnum→OfferTermInfoName, and removed RateCardQueryParameters/UsageAggregationListResult (added UsageSample).
• Updated packaging for the 6.1.0b3 beta: is_stable=false, Development Status :: 4 - Beta, requires-python>=3.10, and refreshed _metadata.json/apiview-properties.json/tsp-location.yaml.
• Public API changes: operation parameters are now keyword-only, send_request/base_url are exposed, and the client uses endpoint templating.

The only issue found is the CHANGELOG entry, which still holds the generator's placeholder text and does not document the breaking changes introduced by this migration.
