REFACTOR: multiple refactors for improving structure and concepts implementations.

[CesarD]

This PR performs several refactors about multiple topics I wanted to improve for some time after some additional experience that I believe should help simplify things in areas like project structure, concepts implementation, samples implementations, etc. as well as including some documentation for the internal libraries.

• REFACTOR: Merged all 3 Application projects into a single one for the sake of simplifying solution structure. Having a single Application project that includes infrastructure configuration and migrations aligns better with the concept of Vertical Slices Architecture and reduces additional structure at the solution level. If required, developers can always split sections of the Application into separate assemblies if required for whatever reason, but Monaco should not early-optimize without additional context. This also helps simplify microservices implementation if desired.
• REFACTOR: Added AggregateRoot base class for differentiating between aggregate roots and other regular entities. Moved domain events into AR to better represent its responsibilities.
• REFACTOR: Separated Entities and ValueObjects into different namespaces.
• REFACTOR: Moved Application DTOs to corresponding feature folders for a better location and maintenance ease.
• REFACTOR: To better match aggregate roots responsibilities, the Product entity has been refactored as its own AR and modified the entire relationship and business logic it had against Company. All related tests and configurations have been modified accordingly.
• DOCS: Documentation has been added to several core classes and components to improve DX.
• CHORE: Dependencies have been updated.
• REFACTOR: CommandResults converted to Records to better represent their concept as DTOs.
• REFACTOR: Worker service project renamed from Service to Worker for better understanding.
• REFACTOR: BlobStorageService refactored to remove temp folder and instead represent the temporal status only in database, making easier the files management at the storage level. No more moving files to make them permanent. Added a path variable to allow setting the path of the blob within the container.
