Create organization onboarding form with validation

Build a multi-step form for organizations to register on the platform. Steps:

1. Organization info: name, type (food bank / shelter / community fridge / other), address
2. Capacity details: storage type (refrigerated / dry / frozen), max capacity in lbs
3. Operating hours and contact info
4. Review and submit

Use React with zod validation at each step. Address should be geocoded to lat/lng on submit (use a free geocoding API). The form should save progress between steps (not lose data on back navigation). Use server components where possible, client components only for interactive steps.
