fix(templates): la página de plantillas no embebía el componente

resources/views/projects/templates.blade.php usaba `<livewire/template-manager>`
(sintaxis inválida; tras la reorganización el alias es `inspections.template-manager`)
y un botón suelto con `$emit` (Livewire 2, fuera de componente) que no hacía nada.
Ahora embebe correctamente <livewire:inspections.template-manager> (que ya trae su
botón "Nuevo" + formulario funcional) y se elimina el botón roto.

Tests: TemplateCreationTest (la página embebe el componente; crear plantilla funciona).
Suite 79 passing.
