Subject: [PATCH] fix: Umlaute, Foto-404, Account-Menu responsive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bugs:
- nginx: /uploads/ wurde von der .jpg/.png-Regex-Location geschluckt
  -> ^~ Prefix gibt /uploads/ und /api/ Vorrang vor Regex
  -> Fotos werden jetzt korrekt vom Backend ausgeliefert
- TopNav menu-item Klasse war via <style>@apply definiert -
  Tailwind verarbeitet @apply nur in .css-Dateien, nicht in JSX-style-Tags
  -> alle Klassen direkt am Element + neuer responsive Aufbau
- TopNav mobile-friendlier: Brand-Truncate, Demo-Badge erst ab sm,
  Dropdown max-w fuer Viewport, Touch-Outside-Close, groessere Touch-Targets

Umlaute:
- Alle ASCII-Substitutionen (fuer, ueber, aendern, loeschen, Stueck, Geraete,
  Ruecknahme, Hintertuer, Schluessel, Kuehlschrank, Pruefe, gueltig, etc.)
  konsequent auf Unicode (für, über, ä, ö, ü, ß) umgestellt.
- 26 Dateien betroffen, SQL-Identifier + Import-Pfade + API-Routen ASCII gelassen.
- seed.js: Baeckerei -> Baeckerei.. ah Baeckerei -> Bäckerei
