Refactor Cosmos DB context configuration and add proxy

Refactored the `ApplicationServices` class to simplify Cosmos DB
context configuration by replacing `AddDbContext` with
`AddCosmosDbContext` and introducing a scoped service registration
for `IGamesRepository` using `DataContextProxy<GamesCosmosContext>`.
Removed `EnrichCosmosDbContext` and commented out old configuration
code for reference.

Added a new `DataContextProxy<TContext>` class to act as a proxy for
`IGamesRepository`, delegating repository operations to the underlying
`DbContext`. This improves flexibility and decouples the repository
interface from specific database context implementations.
