Server-Monitor v3, Composer v2, Temp-Voice-Panel und Embed-Polish

- Server-Monitor v3: gamedig-Integration (300+ Spiele), GSM-Stil-Embeds
  (Spieler-Balken mit %, Map, Spieler-Liste, klickbarer Connect-Link,
  Ping im Footer), Down/Up-Alerts (2 Fails → 🚨, Recovery → ✅ mit
  Downtime) in konfigurierbaren Alert-Kanal; Server-Tab mit 19
  Spiel-Presets, Host/Port bzw. Query-URL und Connect-URL
- Composer v2: visueller Embed-Builder mit Live-Discord-Preview
  (Autor, Felder, Bilder, Farbe, Footer, Timestamp), speicherbare
  Vorlagen (/api/templates), /api/compose versteht volle Embeds
- Temp-Voice: Control-Panel im erstellten Kanal (Umbenennen, Sperren,
  Limit, Löschen) — nur der Kanal-Besitzer darf bedienen
- Embed-Polish: brandEmbed-Factory (src/embeds.js), Footer überall
  mit Bot-Avatar-Icon
