Break everything and introduce i18n

[benoit74]

Code work for #46 and #53 ; translation will then have to be setup on translatewiki

Rationale

• Introduce i18n of the UI and the emails
• Move ui to Vue 3, Vuetify, Pinia, Vue-Router
• Move api to FastAPI, hatch
• Fix many small glitches linked to recent Zimfarm changes
• Enhance some messages
• Upgrade to Node 20 and Python 3.12
• Adapted CI to check code QA on both api and ui + add automated tests
• Split API and UI for proper deployment (two Dockerfile, two packages, adapt CI, ... work on kiwix/operations will follow)

Nota:

• for now PR contains fake and incomplete translations to fr and fa, but these will be dropped before merging, this is used only for testing purpose

That's something! Thank you.

I tested it and it seems to work fine. I was somehow surprised that the UI looks the same 😀

On the python side, I think there are a couple of place with poor type hints (zimfarm module?).

On the Vue part, I mostly skimmed through the code but it looks good and coherent.

On personal taste, I find the user feedback too dim. If there is an error in making a request, theres just a light toast at the bottom of the page that disappears after 5s.
I had to make several requests to see it.

Fixed, thank you

OK, thank you

I think you refer to home page issue, when it fails to fetch offliner definition. This is indeed something I forgot about. I changed the toast to red + I added a message in red as well which stays forever. On the page about the task status, there is a red message when we fail to fetch the task.

(merging because confirmed with rgaudin that further review is not necessary once conversations are taken care of)
