v0.93.0

Added

• Rewards module ("Belohnungen") — a new points-and-rewards system. Tasks can now carry a point value; completing a task credits its assigned members (or the person acting on a shared kiosk tablet when no one is assigned). A household reward catalog lets members redeem points for parent-approved rewards, with opt-in participation per member, manual bonus points, and a full, auditable point ledger where every balance is the sum of its transactions. Includes a per-member standings view, an in-context first-run setup checklist for parents, keyboard/screen-reader access, and animated balance plus toast feedback. All 23 UI languages and the OpenAPI spec cover the new /api/v1/rewards endpoints.
