Allow compose to show container shutdown logs. With an alternative UI.

Description

Containers printing logs on shutdown don't get displayed.

Steps To Reproduce

Example code

package main

import (
    "fmt"
    "os"
    "os/signal"
    "syscall"
)

func main() {
    sigChan := make(chan os.Signal, 1)
    signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM)

    fmt.Println("Hello, World!")

    <-sigChan

    fmt.Println("Goodbye, World!")
}

Example Dockerfile

FROM golang:alpine

WORKDIR /app

COPY . .

RUN go build -o hello .

CMD ["./hello"]

Example compose.yml

services:
  hello:
    build: .

Run docker compose up --build.
Press CTRL + C to gracefully shutdown all the services.
Notice how you won't see the "Goodbye, World!" log but if you run docker compose logs hello, you'll see the log.

I assume it's just detaching too early, causing it not to print the logs, but I don't know if this is intended behavior. To me, this seems like it should print the logs on shutdown.

Forgot to mention, I tested this using docker run, and when I shutdown the container, it does actually print the shutdown logs.

fix(logs): keep log streaming active until containers fully stop

This is something I considered in the past but not a trivial one: as we show progress UI for the stop sequence, we can't mix with logs. Would need to create an alternative progress UI that would not lock access to the terminal. Could show status change events as single line messages + a one-line progress state bar on the bottom (same as menu). Not that simple 😅

Yeah, I understand, that's fair. Hopefully this could get added this in the future, as I feel like it's a feature worth having.
