Implement database storage layer

- Add connection pool configuration (pool_size, max_overflow, timeout, recycle) - Add transaction management utilities (transaction, savepoint, retry_on_deadlock) - Create repository pattern classes for all entities (Project, Package, Artifact, Tag, Upload) - Implement ref_count decrement and cleanup service - Add query helper functions (search, filtering, pagination, stats) - Add database constraints (check_ref_count_non_negative, check_size_positive) - Add performance indexes (idx_artifacts_ref_count, composite indexes for packages/tags) - Initialize Alembic migrations for future schema changes

-> - `-O` saves the file using the URL path as the filename (e.g., `latest`, `v1.0.0`)
-> - `-J` tells curl to use the filename from the `Content-Disposition` header (e.g., `app-v1.0.0.tar.gz`)
