chore: verify CTS API token auth and package compatibility

- Install 5pm-hdh/churchtools-api v2.1.0
- Verify CTConfig::setApiKey() and authWithLoginToken() both available
- Document API response shapes for /api/events and /api/songs
- Confirm CCLI field present, lyrics available, arrangements included
- TDD: CtsApiSpikeTest with 2 tests, 11 assertions - all passing
- Evidence saved to .sisyphus/evidence/task-0-*.txt
- Findings documented in docs/api-response-shapes.md

+# CTS API Spike: Auth + Response Shapes
+
+## Ergebnis
+
+- Paket `5pm-hdh/churchtools-api` ist installiert (`2.1.0`).
+- `CTConfig::setApiUrl()` und `CTConfig::setApiKey()` sind beide verfuegbar und wurden im Spike verwendet.
+- `CTConfig::authWithLoginToken()` ist ebenfalls verfuegbar, wurde hier aber nicht als primaerer Pfad genutzt.
+- Fallback-Strategie ist dokumentiert: Falls Token-Auth ueber das Paket nicht funktioniert, per Raw HTTP mit Header `Authorization: Login <TOKEN>`.
+
+## Auth-Verifikation
+
+Quelle: `.sisyphus/evidence/task-0-api-auth.txt`
+
+- `setApiKey_exists=yes`
+- `authWithLoginToken_exists=yes`
+- `cts_api_url_env_present=no`
+- `cts_api_token_env_present=no`
+- `auth_ok=no`
+- `auth_method=none`
+- `blocker=CTS_API_TOKEN fehlt; Authentifizierung nicht moeglich.`
+
+Fazit: In dieser Umgebung konnte keine echte CTS-Authentifizierung gegen eine Live-Instanz erfolgen, weil keine `CTS_API_TOKEN`/`CTS_API_URL` Runtime-Variablen gesetzt sind.
+
+## Endpoint-Shape: GET /api/events (today+future)
+
+Abfrage im Spike (Package-Request):
+
+- `EventRequest::where('from', 'YYYY-MM-DD')->get()`
+- Daraus entsteht ein Request auf `/api/events` mit Query `from=<date>` und `page=1`.
+
+Mocked Beispiel-Response (relevante Struktur):
+
+```json
+{
+  "data": [
+    {
+      "domainIdentifier": "100",
+      "title": "Gottesdienst Sonntag",
+      "startDate": "2026-03-08T10:00:00+00:00",
+      "note": "Probe"
+    }
+  ],
+  "meta": {
+    "pagination": {
+      "lastPage": 1
+    }
+  }
+}
+```
+
+Abgeleitete Event-Felder im Spike:
+
+- `id` (aus `domainIdentifier`)
+- `title` (string)
+- `start_date` (ISO-String)
+- `note` (string|null)
+
+## Endpoint-Shape: GET /api/songs/1
+
+Quelle: `.sisyphus/evidence/task-0-song-ccli.txt`
+
+- `song_has_ccli=yes`
+- `song_ccli=1234567`
+- `song_has_lyrics=yes`
+- `song_arrangements_count=1`
+- `raw_song_keys=songId,name,ccli,arrangements,lyrics`
+
+Mocked Beispiel-Response (relevante Struktur):
+
+```json
+{
+  "data": {
+    "songId": "1",
+    "name": "Way Maker",
+    "ccli": "7115744",
+    "arrangements": [
+      {
+        "id": "11",
+        "name": "Normal",
+        "isDefault": true
+      }
+    ],
+    "lyrics": {
+      "type": "text",
+      "cclid": "7115744",
+      "lyricParts": [
+        {
+          "key": "v1",
+          "text": "Du bist hier"
+        }
+      ]
+    }
+  }
+}
+```
+
+Fazit Song-Shape:
+
+- `ccli` ist im Song-Response als Feld vorhanden.
+- Lyrics koennen als verschachteltes Objekt (`lyrics`) enthalten sein.
+- Arrangements liegen als Array unter `arrangements`.
+
+## OpenAPI-Download
+
+Zielpfad waere `docs/churchtools-openapi.json` von `<CTS_API_URL>/system/runtime/swagger/openapi.json`.
+
+Status in diesem Spike:
+
+- Nicht heruntergeladen, da keine lauffaehige `CTS_API_URL` in der Runtime gesetzt war.
+- Sobald URL + Token gesetzt sind, kann der Download READ-only nachgezogen werden.
