feat: integrate uload and picture, unify package naming

- Add uload project with apps/web structure
  - Reorganize from flat to monorepo structure
  - Remove PocketBase binary and local data
  - Update to pnpm and @uload/web namespace

- Add picture project to monorepo
  - Remove embedded git repository

- Unify all package names to @{project}/{app} schema:
  - @maerchenzauber/* (was @storyteller/*)
  - @manacore/* (was manacore-*, manacore)
  - @manadeck/* (was web, backend, manadeck)
  - @memoro/* (was memoro-web, landing, memoro)
  - @picture/* (already unified)
  - @uload/web

- Add convenient dev scripts for all apps:
  - pnpm dev:{project}:web
  - pnpm dev:{project}:landing
  - pnpm dev:{project}:mobile
  - pnpm dev:{project}:backend
