Add KV Param to store specialservicereplacements

[bensteUEM]

special service replacements highly depend on the users system configuration and should be changeable e.g. using KV settings

const specialServiceMap: Record<number, string> = {
    89: "Chor",
    92: "Chor",
    93: "Chor",
    96: "Chor",
    54: "InJoy",
    10: "Musikteam",
    61: "Posaunenchor",
    73: "Abendmahl",
    127: "Taufe",
};
