Move all Eloquent models from the app/ root directory to app/Models/
for consistency with modern Laravel conventions. The project already had
54 models in App\Models; this migrates the remaining 52 legacy models.
Changes:
- Move 52 model files from app/ to app/Models/
- Update namespace declarations in each model
- Update all ~1000 import references across the codebase
- Add Relation::morphMap() in AppServiceProvider for backward
compatibility with existing polymorphic database records
- Add missing HasSnowflakePrimary imports for models that relied
on same-namespace resolution
Replace \Cache::, \Log::, \DB:: calls with their imported facade
equivalents. The backslash-prefix relies on global aliases which
PHPStan cannot resolve, causing class.notFound errors.
