Proxy: setup progress stream, self-healing, uninstall, health check cron

- ProxyManager::runSetupOnRemote() — generator yields step-by-step progress; drives SSE stream from /api/proxy/setup-remote POST - ProxyManager::uninstall(bool) — removes configs from remote or local; optionally apt-get removes nginx and sets mode=disabled - ProxyManager::healthCheck() — called every 5 min from collect-stats.php; restarts nginx on remote if found stopped - proxy.php: POST /api/proxy/setup-remote (SSE stream), DELETE /api/proxy/uninstall - admin.js: proxyRunSetup() streams output to a live log modal; proxyUninstall() with configs-only vs full removal choice; 'Run Setup on Remote VM' / 'Uninstall' buttons in page header Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
