refactor: consolidate codebase — remove archived code, deduplicate packages, standardize middleware

- Delete 17 server-archived/ directories (consolidated into apps/api/)
- Delete apps-archived/ (clock, wisekeep) and services-archived/ (it-landing, ollama-metrics-proxy)
- Fix type safety: replace all `any` casts in cross-app-queries.ts with proper Local* types
- Remove duplicate shared-auth-stores package (identical copy of shared-auth-ui/stores/)
- Remove duplicate theme store from shared-stores (canonical version in shared-theme)
- Migrate memoro-server rate-limiter to shared-hono/rateLimitMiddleware
- Migrate uload-server JWT auth + error handler to shared-hono (authMiddleware, errorHandler)
- Migrate arcade-server error handling to shared-hono
- Merge shared-profile-ui and shared-app-onboarding into shared-ui
- Unify /clock route into /times/clock, remove redirect stubs
