Challenge: Official Featured Habitify Team challenges

Allow Habitify to host official, global challenges that any user can join directly from the app. These could appear in a “featured challenges” section and run periodically (for example, “30 Days of Morning Movement” or “Read Daily for 15 Minutes”).

Suggestions:

• Allow both Habitify-hosted challenges and community-hosted challenges.

• Display total participants for motivation. Show users in a top list during challenges, like it used to be.

This would give the Challenges feature a social dimension again - something I as a long‑time users miss.
