chore(deps): bump uvicorn from 0.51.0 to 0.52.0 in /backend

[dependabot]

Bumps uvicorn from 0.51.0 to 0.52.0.

Release notes

Sourced from uvicorn's releases.

Version 0.52.0

This release adds an experimental HTTP/1.1 implementation backed by zttp, a sans-IO HTTP parser I've been developing on the side: a core written in Zig, with bindings to Python. It has been running under a fuzzer for some weeks now, and has been through multiple rounds of security auditing.

It is still experimental, so don't put it in front of production traffic yet. Try it with --http zttp, and please send any feedback to the issue tracker.

Added

• Add an experimental zttp HTTP/1.1 implementation, selectable with --http zttp (#2979)

Fixed

• Keep non-ASCII WebSocket request headers intact with websockets 17.0, which encodes them with ISO-8859-1 (#3036)

Superseded by #27.

A v0.8.7 foi publicada a partir de f11bb53. Na janela validada, o Uvicorn 0.51.0 foi revisado e aplicado de forma independente no commit 64620b9. Depois disso, o Dependabot atualizou esta proposta para 0.52.0 e a substituiu por #27; a versão 0.52.0 não integra a v0.8.7 e precisa de nova revisão independente. Este PR não foi mesclado nem cherry-picked. Fica registrado aqui o desfecho rastreável.
