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
PHP's str_ends_with() only accepts a string needle, not an array.
The username validation was passing an array of extensions which
caused a TypeError on every registration attempt.
Replace with a loop over a configurable array of disallowed extensions,
making it easy to add new entries.
Also updates RegisterTest to properly test the registration flow
including the RT anti-bot token and age verification fields.
