refactor(templates): plantillas globales + asignación por proyecto (pivot)

- Migración: tabla pivot inspection_template_project; drop de phase_id (asociación
  a fase descartada); project_id se mantiene en inspection_templates por compat.
  Migra automáticamente las plantillas existentes (project_id → pivot).
- Modelos: Project::inspectionTemplates() ↔ InspectionTemplate::projects() (BTM);
  retirada la relación phase() de InspectionTemplate.
- GlobalTemplateManager (nuevo, ruta /inspection-templates, permiso manage templates):
  catálogo único global, CRUD + import CSV; sin asociación a fase ni a proyecto.
- ProjectTemplatesPicker (nuevo, ruta projects.templates, permiso edit projects):
  lista global con checkbox para asignar/desasignar plantillas al proyecto.
- ProjectMap: el selector de plantillas del mapa lee SOLO las asignadas al proyecto
  vía pivot. API móvil (bundle + /templates) adaptado al pivot.
- Eliminado el viejo TemplateManager por-proyecto, su vista wrapper y la tabla
  ImportTemplatesTable (ya no aplica: todas son globales).
- Acceso "Plantillas" añadido al menú principal (gate manage templates).

Tests: GlobalTemplatesTest (4). Suite 89 passing.
