Assorted server optimizations

[ml-evs]

This PR adds three optimisations, arising from the (ongoing) talk about optimizing FastAPI/pydantic at EuroPython2023 by Marcelo Tryle.

• Make sure uvloop and httptools are installed alongside uvicorn
• Avoid validating data twice in both the get_entries function and the routes
• Actually fix the validate_api_response option, now that I realise the FastAPI type hints were also validating...
