Support running jetlog under a subdirectory (path prefix)

[SaswatPadhi]

I am running jetlog behing a reverse proxy and would love to be able to host it under a path prefix, say /jetlog. I tried stripping the prefix before forwarding to the server, but couldn't fix a way to tweak the paths internally generated by the app. For example:

<link rel="stylesheet" href="/index.5d77d0b2.css">

should be

<link rel="stylesheet" href="/jetlog/index.5d77d0b2.css">

Not super familiar with the tech stack, but I'd be happy to create a PR if you could point me where to look. Thanks!

Thank you for opening this issue. This problem lies in the server, so FastAPI. Fortunately FastAPI has a way of handling this, by setting the path prefix for the docs, openapi, and static files and routers:

app = FastApi(docs_url = path_prefix + '/docs', 
        openapi_url = path_prefix + '/openapi.json')
app.include_router(router, prefix=path_prefix + '/whatever') # done for each router
app.mount(path_prefix, StaticFiles(...))

That is just a draft of what this change would require, but it's not too hard. A project that uses FastAPI and has done this can be seen here.

Of course we would also need a docker variable to get this prefix from, and its default should be "/" or something. This is also done in the linked project.
