Add Trial Spawner support and improve config handling

Browse Source 
Introduces mixins and accessors for Trial Spawner logic, enabling Silk Touch mining and correct data transfer for Trial Spawners. Refactors config file handling to use FabricLoader and Path APIs for better compatibility. Updates mod metadata, adds a logo, and improves dropped item naming for both spawner types.
