refactor: rename planta → plants, clean up codebase

- Rename planta module to plants everywhere (routes, modules, API,
  branding, i18n, docker, docs, shared packages)
- Fix package name collisions: @mana/credits-service, @mana/subscriptions-service
  (unblocks turbo)
- Extract layout composables: use-ai-tier-items, use-sync-status-items,
  RouteTierGate (layout 1345→1015 lines)
- Create shared DB pool for apps/api (lib/db.ts), migrate 5 modules
- Add automations module queries.ts with useAllAutomations/useEnabledAutomations
- Remove debug console.log statements from production code
- Rename storage display name: Ablage → Speicher
