Accepted breaking changes summary

• ~141 resource/sub-resource models now expose a properties bag instead of flat properties (ARM resource envelope pattern)
• 4 properties renamed with _property suffix to avoid Python built-in collisions
• 37 pageable wrapper models removed (list operations return iterators directly)
• 14 other models removed (common types, enums, patch models, unreferenced types)
