Renommage : TrajetKmTracker -> SchotzIadKmTracker (backend, specs, frontend)

- Backend : projets, solution, namespaces et références
  TrajetKmTracker.Api/.Tests -> SchotzIadKmTracker.Api/.Tests
  (dossiers, .csproj, .sln, .http, namespaces C#). GUID UserSecretsId préservé.
- Specs : dossier .kiro/specs/trajet-km-tracker -> schotziad-km-tracker
  et mise à jour des références internes (chemins, tags de propriétés).
- Frontend : projet Angular trajet-km-tracker -> schotziad-km-tracker
  (package.json, angular.json, chemin dist, Dockerfile), titre applicatif
  'SchotzIAD KM Tracker'.
- Docker et scripts (backend/Dockerfile, frontend/Dockerfile, run-dev.sh) mis à jour.
- Suppression du fichier résiduel package.json.bak.

Backend (solution) et frontend (build production) compilent sans erreur.
