♻️ refactor: migrate 12 backends to shared-nestjs-health module

- Create @manacore/shared-nestjs-health package with HealthModule.forRoot()
- Migrate 12 backends: calendar, chat, clock, contacts, nutriphi, picture,
  planta, presi, skilltree, storage, todo, zitare
- Delete 24 local health controller/module files (~312 LOC removed)
- Support custom route (storage uses 'api/v1/health')
- Skip questions backend (has extended DB health check)
- Fix telegram-zitare-bot missing shared-drizzle-config dependency
- Update CONSOLIDATION_OPPORTUNITIES.md
