Subject: [PATCH] feat: add in-memory database support via appsettings
 UseInMemoryDb flag - Introduced conditional EF Core configuration to support
 InMemoryDatabase for testing or lightweight runs. - Added `UseInMemoryDb`
 config flag read from appsettings. - Retained SQL Server as the default when
 the flag is false. - Added missing Quartz namespace import.
