fix: install linux-musl sharp binaries in Docker (fixes 502 on Alpine)

Browse Source 
The standalone build runs on macOS and bundles darwin-arm64 native
sharp binaries. These crash immediately on the Alpine Linux container,
causing the Node process to exit and Dokploy's reverse proxy to return
a 502 Bad Gateway.

This adds a RUN step to remove the macOS binaries and install the
correct @img/sharp-linuxmusl-x64 package at build time.
