Add auto-loading of module permissions in RolePermissionSeeder

RolePermissionSeeder now automatically scans app/Modules/*/Permissions.php
files and registers all permissions found. No manual registration required.

- Added loadModulePermissions() method to scan module directories
- Changed givePermissionTo() to syncPermissions() for idempotency
- Updated Modules README to document auto-loading
- Updated CLAUDE.md to reflect auto-loading behavior
