Update conf.py with functionalities to specify which special members have to be kept in the documentation.

The name of the `pipelines` module was mistakenly spelled as `piplines`.

There were several places that we had used `mock data` to refer to data generated for testing purposes. This was misleading as we are actually generating the data and the API calls are not mocked. Example `mock_database` is renamed to `test_database`.

As a result, `test_utils` and the `queries` route handler have been also updated.

The new version of FastAPI recommends using `Annotated` for queries. This also resolves the issue with ruff complaining about `Query(None)`.

This led to the removal of some redundant type checks.

The bug had to do with multiple deletion in the recorder. The log message was added to the auto exception handler.

Add two auxiliary methods which simplify the implementation of the main method.

The function is named `make_query_string`

The old name of the function was `parse_config_yaml_file`. The function now accepts a number of different types for the input arg `file`.

This logs and catches unhandled exceptions.

- Remove type hint for `file`.
- Amend docstring.
- Remove explicit exception handling for parsing and reading the file.

As a result, the signature of `run_server()` and
`api_server_process_context()` have been changed.
They now only accept a `config` object of type
`AppConfig`.

The dependencies are now brought after the first main dependent function that uses them.
