Move 26-configure-astrolabe-oauth.sh from post-installation (runs once
on first boot) to before-starting (runs on every start). This ensures
the Astrolabe OIDC client is created as soon as MCP_SERVER_URL is
available, even if it wasn't set during initial installation.
Also copy 25-configure-mcp-server-url.sh to before-starting so the
mcp_server_url config stays current across container recreations.
