+-- Add INSERT policies for reference data tables to enable seeding
+-- These policies allow anyone to insert into reference tables (pokedex_entries, region_game_mappings, metadata)
+-- This is acceptable because:
+-- 1. These are read-only reference data tables for the application
+-- 2. Seeding only happens in development/setup phase
+-- 3. In production, you would typically use service role or disable seeding
