🔧 chore: create @manacore/shared-drizzle-config and migrate 16 configs

- Create factory function with dbName, schemaPath, outDir, schemaFilter options
- Migrate 12 app backends: calendar, chat, clock, contacts, nutriphi, picture,
  planta, presi, questions, skilltree, storage, todo
- Migrate 4 services: mana-core-auth, telegram-zitare-bot, telegram-todo-bot,
  telegram-nutriphi-bot
- Update consolidation docs with completed Drizzle config task

Savings: ~160 LOC (16 configs × ~10 LOC each)
