feat(nextcloud-files): Modul Dateien mit Nextcloud-Adresse, Verbindungsprüfung und gesicherter Verbindungsschicht
- Migration 20261008180000: NextcloudFilesConfig (Organisation) und NextcloudFilesAccount (Mandant UND Benutzer per Zeilenschutz, nur verschlüsseltes App-Passwort) - Transportschicht ncRequest: feste Pfadanfänge, Segmentcodierung, keine Weiterleitungen, keine Cookies, Zeitgrenzen; Aufrufsperre pausiert den Ursprung nach jedem 429 und sperrt Zugangsschlüssel nach dem ersten 401 - Einstellungen: Adresse speichern/prüfen, Adresswechsel läuft alle Konten ab (mit Bestätigung) - Controller mit Verwalten nur auf Einstellungen, Seed, Modul, Registrierung in Web (Ladefunktion, Symbol folder, Navigation, Layout) und Reiter Einstellungen - RLS-Inventar fortgeschrieben, Testaufbau (tessera-nc-test) und E2E-Skripte Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

/**
|
||||
* Einzige Transportschicht des Moduls "Nextcloud-Dateien" (quick-261008-mzu).
|
||||
* Jeder Aufruf an eine Nextcloud geht durch `ncRequest` — dort sitzen die
|
||||
* Schutzregeln, damit sie kein Aufrufer umgehen kann.
|
||||
*
|
||||
* Warum interne Adressen erlaubt sind (L-01): die Nextcloud steht oft im Haus,
|
||||
* und die Adresse setzt allein ein Verwalter. Der gemeinsame Schutz
|
||||
* `isPublicHttpUrl` (nur oeffentliche Adressen) wird deshalb hier mit Absicht
|
||||
* NICHT verwendet. Stattdessen wird die Reichweite so eingegrenzt:
|
||||
* - Es gibt genau EINE Basisadresse je Organisation (Normalform von
|
||||
* `normalizeCloudUrl`). Jede URL ist `Basis + fester Pfadanfang +
|
||||
* einzeln codierte Segmente`; der Pfadanfang kommt aus einer festen Liste.
|
||||
* - Benutzereingaben sind nur Pfadsegmente. Sie laufen durch
|
||||
* `validateSegment` und werden Stueck fuer Stueck mit `encodeURIComponent`
|
||||
* codiert (nie ein ganzer Pfad auf einmal).
|
||||
* - Es werden KEINE Weiterleitungen befolgt (jedes 3xx ist ein Fehler), und
|
||||
* nie wird eine URL aus einer Nextcloud-Antwort aufgerufen.
|
||||
* - Es werden nie Cookies gesendet; `set-cookie` wird nie weitergereicht.
|
||||
* - Zeit- und Groessengrenzen auf jedem Aufruf. Zertifikate werden immer
|
||||
* geprueft (es gibt keinen Schalter, das abzustellen; eine interne CA
|
||||
* gehoert in `NODE_EXTRA_CA_CERTS` des api-Containers).
|
||||
* - Ein Adresswechsel laesst alle gespeicherten App-Passwoerter ablaufen,
|
||||
* das Konto fuehrt die Adresse mit, fuer die das Passwort galt.
|
||||
*
|
||||
* Warum undici `request` und nicht `fetch`: Node-Streams als Anfragekoerper
|
||||
* ohne Umweg, kein Weiterleitungsfolgen von sich aus, die Antwort kommt als
|
||||
* lesbarer Strom, der mit `stream.pipeline` weitergereicht werden kann.
|
||||
*
|
||||
* Nie loggen: Kopfzeilen, Zugangsdaten, App-Passwoerter. Fehlerergebnisse
|
||||
* tragen nur Art, Statuscode und eine kurze Kennung (z. B. `ENOTFOUND`).
