feat!: Drop support for the legacy Group Configurations page.

The legacy Group Configurations page in Studio has been replaced with
a new view in the Authoring MFE. This change removes the now unused
JS/HTML/Python related to the old page.

This work is part of #36108

BREAKING CHANGE: The 'legacy_studio.configurations' waffle flag will
no longer be respected. The system will behave as if the flag is set to
false permanently.
