refactor: universal logger and remove N+1 catalog queries

- Replace all 39 console.* calls with universal logger (pino server, console browser)
- Set server-only marker on import-badge.ts
- Disable DB query logging in production
- Add bulkInsertCatalogItems: one transaction instead of N per-item inserts
- Add reserveCatalogItemIds helper for bulk ID allocation
- Optimize translateCatalogItems: single inArray batch query instead of N per-item selects
- Test mock updated for logger.debug
- biome clean, tsc clean, 3569 tests passing
