[Bug] Broken GHCR mirror (ghcr.1panel.live) hardcoded in app-management causes installation failures #617

Problem Description

When installing applications that use GitHub Container Registry (ghcr.io), casaos-app-management / ZimaOS automatically rewrites or proxies the registry URL to ghcr.1panel.live.

Currently, the domain ghcr.1panel.live is completely unreachable / down, causing all ghcr.io image pulls to fail with DNS/network lookup errors.

Error Output

Error response from daemon: Get "https://ghcr.1panel.live/v2/": dial tcp: lookup ghcr.1panel.live: no such host

Steps to Reproduce

1. Attempt to install any custom Docker Compose stack using images from ghcr.io (e.g., ghcr.io/toeverything/affine-node:stable).
2. Watch the installation fail during the image pull stage.

Expected Behavior

ZimaOS should pull directly from ghcr.io or allow configuring/disabling third-party registry mirrors in the settings, rather than falling back to an unmaintained third-party proxy (1panel.live).

Suggested Fix

Remove ghcr.1panel.live from the hardcoded registry mirror/proxy map in casaos-app-management or update it to pull directly from ghcr.io.
