drop laravel scaffold defaults

removed app/Models/User.php (laravel auth model - tide authors a
ddd User entity in app/User/), app/Http/Controllers/Controller.php
(controllers live flat in app/Controllers/ per youngstartup), and
all three 0001_01_01_* migrations (default users schema, cache,
jobs - tide writes its own users migration with is_admin and
password_hash). routes/api.php stripped of the sanctum-bound
/user demo route - left as an empty stub for incoming domains.
