feat(logs): add Logs Dashboard with real-time Console Viewer

- Consolidated 4-tab Logs page: Request Logs, Proxy Logs, Audit Logs, Console
- Terminal-style Console Log Viewer with level filter, search, auto-scroll
- Console interceptor captures all console.log/warn/error to JSON log file
- Integrated in Next.js instrumentation.ts for both dev and prod
- Log rotation by size + retention-based cleanup
- Fixed pino logger file transport (pino/file targets only)
- Moved initAuditLog() to instrumentation.ts for proper initialization
- Bumped version to 1.0.3
- Updated CHANGELOG, all 8 README translations, and .env.example
