Fixed request context bug, silenced Ruff warnings

[shawnsw]

Fixing the following error:

    return self.templates.TemplateResponse(name=template_name, request=request, context=result)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Jinja2Templates.TemplateResponse() got an unexpected keyword argument 'request'

The error is due to how the TemplateResponse is being constructed in the render function within the Jinja class. Specifically, the error arises because the TemplateResponse method is being called with an incorrect argument: request=request. The request should be part of the context dictionary, not passed as a separate argument.

Also fixed some obvious Ruff warnings and silenced the rest non-critical comment related warnings.
