build: move to uv (#488)

* build: move to uv

* build: add packages declaration

* build: move to python 3.12, as sentencespiece does not work on 3.13

* ci: remove pre-commit check, will be done in another branch.

* ci: fix name checkout

* ci: update lock and dockerfile

* test: remove event_loop, not needed in python 3.12

* test: updated test due to av returning AudioFrame with 4096 samples instead of 1024

* build: prevent using fastapi cli, because there is no way to set default port

I don't want to pass --port 1250 every time, so back on previous
approach. I deactivated auto-reload for production.

* ci: remove main.py

* test: fix quirck with httpx
