supabase schema

this app uses supabase to store user-generated data across three tables:

• notifications: logs custom alerts with a message and timestamp
• pins: stores dropped pins with location and category type
• camera_posts: saves compressed images and their ai-generated captions

each table uses a uuid primary key and timestamps for tracking.
