Pull request overview

This PR refreshes the azure-mgmt-databox management package by regenerating it from TypeSpec (previously AutoRest), moving from API version 2025-02-01 to 2025-07-01 and bumping the package from 3.1.0 to the beta 4.0.0b1. It migrates packaging from setup.py/sdk_packaging.toml into pyproject.toml, consolidates operation modules, and adds cloud-aware ARM endpoint handling to the client.

Changes:

• Regenerated client/models/operations from TypeSpec; consolidated operations into _operations.py, removed _vendor.py and legacy per-operation modules, and added a _utils serialization package.
• Introduced new client capabilities (cloud_setting, public send_request, etag/match_condition for begin_update) and reshaped several models around properties containers, documented as breaking changes in the CHANGELOG.
• Migrated packaging metadata to pyproject.toml (Python >=3.10, azure-mgmt-core>=1.6.0), updated README to Python 3.10+/Microsoft Entra, and refreshed generated tests/samples to the new API version.
