Build a step type

Apps can suggest a daily step on an event Quest already verifies. A staff review is required before it can appear in a daily quest.

1. Get an app token for openvibe.quest with quest.steps.contribute.
2. Choose a topic from the registry. The event must identify the person who did it.
3. POST JSON to /api/v1/step-types with id, event_type, site, sentence, href and weight (1–5).
4. The API returns a pending type. Staff reviews it before the generator can select it.

Each selected step needs one real event in the person's local day. The API gives the same quest to everyone; each person's progress remains private.
