Add delay information display for pending messages in MessengerBundle

[Copilot]

Summary

This PR adds support for displaying delayed message information in the MessengerBundle admin interface, addressing the feature request where messages dispatched with DelayStamp were not showing any indication of their delayed status.

Changes

• Added delay property to MessageDetails class to track message delay information
• Updated MessageRepository to extract DelayStamp information from message envelopes
• Use Carbon's diffForHumans for human-readable delay formatting with multiple parts (e.g., "1 day 2 hours")
• Updated frontend JavaScript to display the "Delay" column in pending messages grid
• Added translations for the new column header (English and German)
• Passed code review
• Passed CodeQL security checks

How it works

When messages are dispatched with a DelayStamp, the delay duration is extracted from the envelope and displayed using Carbon's diffForHumans method (e.g., "1 day 2 hours"). Messages without a delay stamp will show an empty delay column, indicating they are available for immediate processing.

<issue_description>| Q | A
| ---------------- | -----
| Bug report? | probably not
| Feature request? | probably yes
| BC Break report? | no
| RFC? | maybe

This issue lives in the gray area between a bug and a missing feature, so not sure how to answer with a clear yes-no above :) Leaning towards a feature request.

Dispatching a message like this with a delay to the availability will cause it to not show in the MessengerBundle interface leading to questions like "did it actually register in the system?"

Should they show? At least as a pending message, right? But maybe not as any other message with immediate availability? What do you think, what is a good way to solve it?

use App\Model\Messenger\ProductFetchMessage;
use Symfony\Component\Messenger\MessageBusInterface;
use Symfony\Component\Messenger\Stamp\DelayStamp;

class FooMessageHandler
{
    public function __construct(private MessageBusInterface $bus) {}

    public function someAction(): void
    {
        $this->bus->dispatch(
            new ProductFetchMessage($itemVariant->getId()),
            [new DelayStamp(86_400_000)]
        );
    }
}

Comments on the Issue (you are @copilot in this section)

@dpfaffenbauer @NiklasBr yes, I would count that as a missing feature @dpfaffenbauer something like this, we can still add to 3.2.x and merge up to 4.0.x and 4.1.x. Only bigger things is what we only do for new minor releases.

I think for this method @copilot can try to use

use Carbon\Carbon;
use Carbon\CarbonInterface;

$diff = Carbon::now()->subMilliseconds($delayMs);
return Carbon::now()->diffForHumans(other: $diff, syntax: CarbonInterface::DIFF_ABSOLUTE, parts: 2);

:D

Updated to use Carbon's diffForHumans in commit fb7f167. The delay is now formatted with up to 2 parts (e.g., "1 day 2 hours").
