- Refactor migrations and provider to use multiple PostgreSQL schemas, each matching a legacy SQLite database (activitylog, authentication, displaypreferences, library, users). - All tables, foreign keys, and indexes are now schema-qualified; Down migration drops tables by schema. - Provider ensures schemas exist before migrations; entities are mapped to correct schemas in OnModelCreating. - Add support for max-pool-size, min-pool-size, and multiplexing connection options; update logging accordingly. - VACUUM ANALYZE now runs per schema during scheduled optimization. - TruncateAllTablesAsync now truncates tables with schema qualification. - README updated with schema structure, new options, and multiplexing warnings. - CacheDecorator now calls async repository methods using .GetAwaiter().GetResult(), with documentation. - Lays groundwork for full async/await and multiplexing support in the database layer.
