feat: use Supabase JSONB column for asset requests storage

- Add SQL query to create asset_requests_data JSONB column
- Store all asset requests in InvestorAgent/2025-08-01/BTC row
- Update AddAssetView to read/write from Supabase
- Update AssetRequestsView to display and vote via Supabase
- All users can now see and vote on shared asset requests
