Work on Ticket: #43
feat(api): align REST endpoints with gRPC, introduce DTOs and refactor controllers

• Added missing REST endpoints for full parity with gRPC:

  • GET /api/models
  • PUT /api/ModelConfigurations/{instrument}/config/random-additive-walk
  • GET /api/prices/{instrument}/history

• Refactored existing controllers to use IInstrumentModelManager:

  • Replaced direct DbContext access with business logic layer
  • Ensures consistent validation, default config creation and event triggering

• Introduced DTOs across controllers:

  • Replaced entity responses with typed response DTOs
  • Added request DTOs for all update/create operations
  • Standardized update responses via UpdateConfigResponseDto

• Aligned REST responses with gRPC semantics:

  • Consistent message + success flags
  • Matching field names and structures (e.g. ActiveModel, TickIntervalMs)
  • Unified configuration response structure

• Improved API consistency and maintainability:

  • Removed anonymous object responses
  • Centralized mapping logic via DTO mappers
  • Prepared controllers for proper OpenAPI/Swagger documentation

Could you please add back the csproj

[szigh]

I think this was a mistake

We need to update the test project to use the new DTOs - it shouldn't be a big task but let me know if you can't do it and I will update.

Same with adding new tests for the new endpoints you added.

Good idea using the same service that gRPC uses (rather than directly accessing the dbContext)

• adding a third controller is a good shout. I will probably do the same with proto at some point (3 controllers/protos for Instruments+Models+Prices).

Thanks for the contribution

@szigh I’m so sorry, but I’ve unfortunately fallen ill, so my work will be a little delayed. If you don’t mind waiting, I’ll finish everything as soon as I’m back! However, if you’d like to finish earlier, you’re welcome to start on the test cases yourself. Thank you so much for your understanding!
