App-Namen im iOS-Projekt auf VanControl vereinheitlichen

CamperMonitor (Haupt-Repo) und VanAligneiOS (aus dem gemergten
solar-integration-Branch) liefen unter zwei verschiedenen internen
Namen, obwohl die App nach aussen längst einheitlich "VanControl Pro"
heisst. Jetzt durchgängig VanControl:

- Ordner: CamperMonitor/, CamperMonitorWatch/, CamperMonitorComplication/,
  VanAligneiOSWidget/ → VanControl/, VanControlWatch/,
  VanControlComplication/, VanControlWidget/
- Xcode-Projekt: CamperMonitor.xcodeproj → VanControl.xcodeproj, alle
  Targets/Schemes/Produktnamen entsprechend umbenannt
- Bundle-Identifier auf Wunsch mitgeändert: de.s0.fototeddy.VanControl*
  (App noch nicht veröffentlicht); dabei auch die
  WKCompanionAppBundleIdentifier-Werte korrigiert, die noch das alte
  de.fritob-Präfix statt des tatsächlichen de.s0.fototeddy-Präfixes
  trugen
- Swift-Dateien/Typen: CamperMonitorApp → VanControlApp,
  VanAligneiOSWidget* → VanControlWidget*
- Config/*-Info.plist umbenannt, README.md/Tools/README.md/run-tests.sh
  auf die neuen Pfade angepasst

Bewusst unverändert: firmware/vanalign und alle Bezüge auf "VanAlign"
als Namen der Neigungsmesser-Hardware (eigenständiges Produkt, kein
App-Name) sowie der komplette Android/-Ordner.

Build (App, Watch, Debug) und Protokoll-Testlauf grün.
