* feat(key_management_endpoints.py): adding support for rotating master key * feat(key_management_endpoints.py): support decryption-re-encryption of models in db, when master key rotated * fix(user_api_key_auth.py): raise valid token is None error earlier enables easier debugging with api key hash in error message * feat(key_management_endpoints.py): rotate any env vars * fix(key_management_endpoints.py): uncomment check * fix: fix linting error
