Feature/devexp 1324 sms api groups

[marcos-sinch]

• Implements all 7 SMS Groups API operations: create, list, get, replace, update, delete, list_members

• Removes deprecated dataclass-based groups and inbounds stubs (models/groups/, models/inbounds/) predating the v1 Pydantic layer

Not related to this PR, but the main branch still contains old groups/inbounds directories: https://github.com/sinch/sinch-sdk-python/tree/main/sinch/domains/sms/models released with 0.1.0 version

Is timing if goo to remove them ?

I see two options: open a dedicated PR on main to remove them now, or wait and include the cleanup in the 2.1.0 release, this files are already removed in this PR. — what do you think?
