refactor: update database setup and remove skills migration API

- Changed migration commands in DATABASE_SETUP.md to use `pnpm run sync-skills` and `pnpm run sync-teams`.
- Removed the skills migration API endpoint in route.ts, streamlining the migration process.
- Updated MIGRATION_UUID.md to reflect changes in migration steps and removed the old skills migration script.
- Added new sync scripts for skills and teams in package.json.
- Cleaned up init.sql by removing old teams data insertion and adjusted comments for clarity.
