integrate inspection planning with backend API

Inspection planning – backend integration

New: inspectionPlanningStore.ts – Zustand store that calls /api/inspections/planning for:

• GET – list planning items (paginated)
• POST – create planning item
• PATCH /{uuid}/status – update status
• DELETE /{uuid} – delete planning item

Updated: view.tsx – planning screen now:

• Loads planning items from the API on mount and when the week changes
• Creates inspections via POST with validation (vehicle, responsible, date, time)
• Updates status inline via PATCH
• Deletes items via DELETE
• Shows success/error snackbars for all actions
