Code Review

This pull request adds three new partners ("Mobify", "Hyper Pixel", and "Mabiloft") to the partners YAML configuration. The review feedback highlights a critical missing required field options_GCP_partner for "Hyper Pixel" that would cause runtime parsing failures, as well as minor grammatical corrections for the summaries of "Mobify" and "Mabiloft".
