Cadwyn

Fixed

* Whenever a route was migrated by path, we used the path and methods of the request. So if the request wanted "/v1/webhook_settings" and we renamed them to "/v1/webhook_subscriptions" -- all migrations for "/v1/webhook_subscriptions" would not get applied to any requests that wanted "/v1/webhook_settings". This effectively means that previously route renamings were incompatible with by path converters. Now we use the head route id instead of the path and methods of the request for matching so we always know which migrations to apply.

Fixed

* [268](https://github.com/zmievsa/cadwyn/issues/268) A bug where we received 404 for all unversioned routes when a default api version was passed to Cadwyn at initialization

Removed

* `issubclass` dependency

Fixed

* a bug where a custom HTTP exception was not being copied correctly so its unique properties are ignored

Fixed

* `__doc__` attribute is now copied from the original enum to the generated enum
* Python 3.12 type aliases and their typing_extensions backports are now supported (including `pydantic.JsonValue` and other `typing_extensions.TypeAliasType` instances)
* The bug when solve_dependencies error on the migration of a request to the latest version responds with a non-json serializable error and cadwyn showed a failed to serialize error instead of the actual error
* Updated minimum fastapi version to 0.112.4 because embed_body_fields was added in 0.112.4

Fixed

* Generators not being called when fastapi validates the initial request

Added

* `cadwyn.current_dependency_solver` function to check whether cadwyn or fastapi is currently solving dependencies. It can be used as a dependency for versioned endpoints like so: `current_dependency_solver: Annotated[Literal["fastapi", "cadwyn"], Depends(current_dependency_solver)]`. If your dependency has side effects, you would likely want to only run it once per request. If you want to run it once we migrated the request to the latest version, you should only run it when `current_dependency_solver` is `"cadwyn"`. If you want your dependency to run at the very beginning of handling the request, you should only run it when `current_dependency_solver` is `"fastapi"`.
