🚀 Faster & more accurate server-ready detection

🚀 Faster & more accurate server-ready detection

Previously, the manager waited after RCON first responded before marking a server as "Running" — a fixed safety buffer that made all servers look slow to start, especially on lower-end hardware.

Now the manager reads the server's own ShooterGame.log and watches for the same line ARK prints to its console when it's truly ready:

Server has completed startup and is now advertising for join

The moment that line appears, the server is instantly marked "Running" — no more arbitrary wait.

Changes:

• ⚡ Removed the RCON hearthbeats at server start
• 🎯 Server status now reflects the server's actual startup completion, detected directly from its log file
• 🛡️ Watchdog (boot timeout & crash/frozen-map detection) is unchanged and still active as a safety net
