Add modular app structure for L1 server refactoring

Phase 2 of the full modernization: - App factory pattern with create_app() - Settings via dataclass with env vars - Dependency injection container - Router stubs for auth, storage, api, recipes, cache, runs - Service layer stubs for run, recipe, cache - Repository layer placeholder Routes are stubs that import from legacy server.py during migration. Next: Migrate each router fully with templates. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
