Branding-Tab: Name/Farben/Bot-Status/Avatar/Banner + Button-Farben für Rollen-Menüs

- Alle Embeds nutzen jetzt brandName/brandColor/brandColor2/brandFooter aus den
  Settings (Codemod über 20 Module) — Farbe & Name serverweit per Klick änderbar
- Bot-Status (Presence): Typ (Spielt/Schaut/Hört/Status) + Text, sofort angewendet;
  Server-Monitor nutzt die Presence nur noch, wenn kein eigener Status gesetzt ist
- Avatar-/Banner-Upload direkt aufs Bot-Profil (Base64, 8-MB-Limit,
  Discord-Rate-Limit sauber gemeldet)
- Env-Verlagerung: GITEA_API_TOKEN (write-only Setting) und DISCORD_GUILD_ID
  jetzt auch über den Brand-Tab pflegbar — weniger Redeploys
- Rollen-Menüs: Button-Farbe pro Eintrag wählbar (Grau/Blau/Grün/Rot)
