Refactor database layer to eliminate type switching and simplify architecture

- Replace type switching with clean repository pattern using sqlc-generated code - Move ContentRepository interface and domain models to db package - Create separate SQLiteRepository and PostgreSQLRepository implementations - Remove unnecessary RepositoryAdapter and ContentClient interface duplication - Update all clients (HTTP, Mock) to implement db.ContentRepository directly - Add context.Context parameters to all repository methods (Go best practice) - Eliminate duplicate domain models and type conversions - Remove type aliases - use db package types directly throughout codebase - Update engine, content managers, and API handlers to use repositories directly Benefits: - Zero runtime type switching overhead - Single source of truth for domain models - Clean package boundaries and separation of concerns - Standard Go interface patterns with context support - Easier testing with mockable repository interface - Maintainable: adding new database types requires no changes to existing code
