Pull request overview

This PR refreshes azure-mgmt-datafactory after its migration to TypeSpec, promoting the package from beta (10.0.0b1) to its stable GA release (10.0.0). It advances the spec commit and emitter version, regenerates the operations/serialization code, and updates packaging metadata to reflect the stable status. It fits into the repo's ongoing TypeSpec migration effort for management-plane SDKs.

Changes:

• Promote to stable GA: bump _version.py to 10.0.0, set is_stable = true, switch classifier to Development Status :: 5 - Production/Stable (and add Python 3.14), with a matching ## 10.0.0 (2026-07-07) CHANGELOG entry.
• Regenerate operations to use the new emitter types.py TypedDict request types (_types) in place of the old JSON = MutableMapping alias, and add numeric duration serialize/deserialize helpers to the generated _utils runtime.
• Update spec/emitter metadata (tsp-location.yaml, _metadata.json, apiview-properties.json, new api.metadata.yml) and rebrand the README auth section from "Azure Active Directory" to "Microsoft Entra".
