refactor: add declare(strict_types=1) to remaining PHP files

Add strict_types declaration to 9 scaffold/config files that were
missed in the earlier dx-audit pass (bcb40d4). All non-blade PHP
files in the repository now enforce strict typing per CLAUDE.md
conventions.

Files: bootstrap/app.php, bootstrap/providers.php, config/core.php,
database/seeders/DatabaseSeeder.php, public/index.php, routes/*.php,
app/Providers/AppServiceProvider.php

Fixes #5
