feat: Set up npm workspace structure for DBAL integration

Workspace Setup Complete:
- Added dbal/development to root package.json workspaces
- Added @metabuilder/dbal dependency to frontends/nextjs (file reference)
- Updated TypeScript paths in frontend to resolve via node_modules
- Installed workspace dependencies successfully

Structure Now In Place:
✅ dbal/development is registered as workspace
✅ @metabuilder/dbal dependency declared in frontend
✅ Path aliases configured for @/dbal resolution
✅ npm install works with all dependencies

Pre-existing DBAL Build Issues Found:
⚠️ src/core/foundation/types/types.generated missing
⚠️ CodeGen script (tsx ../shared/tools/codegen/gen_types.ts) failing
⚠️ exactOptionalPropertyTypes causing TypeScript errors in KV operations

These are pre-existing issues in DBAL code, not related to workspace setup.
Will need separate DBAL build fix task.

For now, workspace structure is ready for when DBAL build is fixed.
